Welcome to this video on simplifying rational expressions.<\/p>\n<h2><span id=\"What_is_a_Rational_Expression\" class=\"m-toc-anchor\"><\/span>What is a Rational Expression?<\/h2>\n<p>\nA <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/rational-expressions\/\">rational expression<\/a> just refers to a <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/fractions\/\">fraction<\/a> with a polynomial in the numerator, and a polynomial in the denominator.<\/p>\n<h3><span id=\"Rational_Expression_Examples\" class=\"m-toc-anchor\"><\/span>Rational Expression Examples<\/h3>\n<p>\nHere are a few examples:<\/p>\n<ol>\n<li style=\"margin-bottom: 1.25em;\"><span style=\"font-size: 125%;\">\\(\\frac{x^{2}-16}{x+4}\\)<\/span><\/li>\n<li style=\"margin-bottom: 1.25em;><span style=\"font-size: 125%;\">\\(\\frac{x^{2}-2x-8}{x^{2}-9x+20}\\)<\/span><\/li>\n<li><span style=\"font-size: 125%;\">\\(\\frac{4x+4}{x^{4}-x^{2}}\\)<\/span><\/li>\n<\/ol>\n<p>One thing that we need to keep in mind when working with rational expression is that divisibility by 0 is not allowed. Just like when dealing with regular numbers, you cannot divide by 0. So, when dealing with a rational expression, we always assume that whatever \\(x\\) is, it will not give us division by 0.<\/p>\n<h2><span id=\"How_to_Reduce_Rational_Expressions\" class=\"m-toc-anchor\"><\/span>How to Reduce Rational Expressions<\/h2>\n<p>\nAlright let\u2019s take a look at how to reduce a rational expression. We&#8217;re actually doing the same thing we would do when reducing a regular fraction.<\/p>\n<h3><span id=\"Example_1\" class=\"m-toc-anchor\"><\/span>Example #1<\/h3>\n<p>\nSo, let\u2019s say we have \\(\\frac{18}{8}\\). When we reduce this, we can cancel our like terms. So we can rewrite this as:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(\\frac{9(2)}{4(2)}\\)<\/div>\n<p>\n&nbsp;<br \/>\nWe can cancel our 2s here giving us:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(\\frac{9}{4}\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo now we have a fraction reduced down to its simplest form. There is not another number that both our numerator and denominator are divisible by.<\/p>\n<p>It works the same way with a rational expression.<\/p>\n<p>Let\u2019s try reducing our first example.<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(\\frac{x^{2}-16}{x+4}\\)<\/div>\n<p>\n&nbsp;<br \/>\nWe can rewrite our numerator, once we factor this out, as:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(\\frac{(x+4)(x-4)}{(x+4)}\\)<\/div>\n<p>\n&nbsp;<br \/>\nAnd once we do this, we can see that our \\((x+4)\\)s will cancel out. So we cancel that out, leaving us with \\(x-4\\)<\/p>\n<p>Now, we need to be careful when canceling terms. The only reason we were able to cancel out our \\((x+4)\\)s here was because they are both being multiplied in the numerator and the denominator. This would not work if our top was: \\(\\frac{(x+4)+(x-4)}{(x+4)}\\).<\/p>\n<h3><span id=\"Example_2\" class=\"m-toc-anchor\"><\/span>Example #2<\/h3>\n<p>\nLet\u2019s now move on to our second example, which is a bit trickier.<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(\\frac{x^{2}-2x-8}{x^{2}-9x+20}\\)<\/div>\n<p>\n&nbsp;<br \/>\nWe can do the same thing that we did in our first example by rewriting our numerator and denominator. So that would give us:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(=\\frac{(x-4)(x+2)}{(x-5)(x-4)}\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo, we can go ahead here and cancel our \\((x-4)\\)s, which would leave us with:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(=\\frac{x+2}{x-5}\\)<\/div>\n<p>\n&nbsp;<\/p>\n<h3><span id=\"Example_3\" class=\"m-toc-anchor\"><\/span>Example #3<\/h3>\n<p>\nFor our last example we have:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(\\frac{4x+4}{x^{4}-x^{2}}\\)<\/div>\n<p>\n&nbsp;<br \/>\nTo reduce it, we can rewrite our numerator by factoring out a 4, which would give us \\(4(x+1)\\). In the denominator we can factor out an \\(x^{2}\\), which would give us \\(x^{2}(x^{2}-1)\\).<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(=\\frac{4(x+1)}{x^{2}(x^{2}-1)}\\)<\/div>\n<p>\n&nbsp;<br \/>\nBut, notice, we can factor this out even further so we can get something to cancel out with our numerator here.<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(=\\frac{4(x+1)}{x^{2}(x+1)(x-1)}\\)<\/div>\n<p>\n&nbsp;<br \/>\nAt this point, we can cancel out our \\((x+1)\\)s here, leaving us with:<\/p>\n<div class=\"examplesentence\" style=\"font-size: 125%;\">\\(=\\frac{4}{x^{2}(x-1)}\\)<\/div>\n<p>\n&nbsp;<br \/>\nThere is no further reduction we can do, so we now have it in our simplest form.<\/p>\n<hr>\n<p>\nI hope that this video has been helpful for you!<\/p>\n<p>See you guys next time!<\/p>\n<\/div>\n<div class=\"spoiler\" id=\"PQs-spoiler\">\n<h2 style=\"text-align:center\"><span id=\"Rational_Expression_Practice_Questions\" class=\"m-toc-anchor\"><\/span>Rational Expression Practice Questions<\/h2>\n\n\t\t\t\t<div class=\"PQ\">\n\t\t\t\t\t<strong>Question #1:<\/strong>\n\t\t\t\t\t<div style=\"margin-left:10px;\"><p>&nbsp;<br \/>\nCan the fraction below be reduced?<\/p>\n<div class=\"yellow-math-quote\">\\(\\dfrac{x+8}{x-8}\\)<\/div>\n<\/div>\n\t\t\t\t\t<div class=\"PQ-Choices\"><div class=\"PQ\"  id=\"PQ-1-1\">Yes<\/div><div class=\"PQ correct_answer\"  id=\"PQ-1-2\">No<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<input id=\"PQ-1\" type=\"checkbox\" class=\"spoiler_button\" \/><label for=\"PQ-1\" style=\"width: 150px;\">Show Answer<\/label>\n\t\t\t\t\t<div class=\"answer\" id=\"PQ-1-spoiler\">\n\t\t\t\t\t\t<strong>Answer:<\/strong><div style=\"margin-left:10px;\"><p>You cannot cancel out anything between the numerator and the denominator because we\u2019re adding 8 in the numerator and subtracting by 8 in the denominator.
