This method is primarily used in algebra to simplify expressions, solve equations, and analyze functions.\r\n\r\nImagine that we are trying to find the area of a lawn so that we can determine how much grass seed to purchase. The lawn is the green portion in the figure below.\r\n\r\n[caption id=\"\" align=\"aligncenter\" width=\"487\"]<img src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images\/wp-content\/uploads\/sites\/896\/2016\/10\/21210700\/CNX_CAT_Figure_01_05_001.jpg\" alt=\"A large rectangle with smaller squares and a rectangle inside. The length of the outer rectangle is 6x and the width is 10x. The side length of the squares is 4 and the height of the width of the inner rectangle is 4.\" width=\"487\" height=\"259\" \/> Geometric figure used to calculate shaded area by removing known dimensions (4 \u00d7 4) from a 10x by 6x rectangle.[\/caption]\r\n\r\nThe area of the entire region can be found using the formula for the area of a rectangle.\r\n<p style=\"text-align: center;\">[latex]\\begin{array}{ccc}\\hfill A&amp; =&amp; lw\\hfill \\\\ &amp; =&amp; 10x\\cdot 6x\\hfill \\\\ &amp; =&amp; 60{x}^{2}{\\text{ units}}^{2}\\hfill \\end{array}[\/latex]<\/p>\r\nThe areas of the portions that do not require grass seed need to be subtracted from the area of the entire region. The two square regions each have an area of [latex]A={s}^{2}={4}^{2}=16[\/latex] units<sup>2<\/sup>. The other rectangular region has one side of length [latex]10x - 8[\/latex] and one side of length [latex]4[\/latex], giving an area of [latex]A=lw=4\\left(10x - 8\\right)=40x - 32[\/latex] units<sup>2<\/sup>. So the region that must be subtracted has an area of [latex]2\\left(16\\right)+40x - 32=40x[\/latex] units<sup>2<\/sup>.\r\n\r\nThe area of the region that requires grass seed is found by subtracting [latex]60{x}^{2}-40x[\/latex] units<sup>2<\/sup>. This area can also be expressed in factored form as [latex]20x\\left(3x - 2\\right)[\/latex] units<sup>2<\/sup>. We can confirm that this is an equivalent expression by multiplying.\r\n\r\nMany polynomial expressions can be written in simpler forms by factoring.\r\n<h2>Factoring the Greatest Common Factor

This method is primarily used in algebra to simplify expressions, solve equations, and analyze functions.<\/p>\n<p>Imagine that we are trying to find the area of a lawn so that we can determine how much grass seed to purchase. The lawn is the green portion in the figure below.<\/p>\n<figure style=\"width: 487px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images\/wp-content\/uploads\/sites\/896\/2016\/10\/21210700\/CNX_CAT_Figure_01_05_001.jpg\" alt=\"A large rectangle with smaller squares and a rectangle inside.
