There are two standard patterns to recognize for perfect square trinomials:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>a\u00b2 + 2ab + b\u00b2 = (a + b)\u00b2<\/li>\n\n\n\n<li>a\u00b2 &#8211; 2ab + b\u00b2 = (a &#8211; b)\u00b2<\/li>\n<\/ol>\n\n\n\n<p>To factor the given expression, x\u00b2 &#8211; 8x + 16, we need to determine if it fits one of these patterns.<\/p>\n\n\n\n<p><strong>Step 1: Identify the &#8216;a&#8217; and &#8216;b&#8217; terms.<\/strong><br>First, we look at the first and last terms of the trinomial to see if they are perfect squares.<br>The first term is x\u00b2. This is the square of x. So, we can set&nbsp;<strong>a = x<\/strong>.<br>The last term is 16. This is the square of 4. So, we can set&nbsp;<strong>b = 4<\/strong>.<\/p>\n\n\n\n<p><strong>Step 2: Check the middle term.<\/strong><br>Now, we must verify if the middle term, -8x, matches the pattern. Since the middle term is negative, we should check it against the second formula&#8217;s middle term, which is -2ab.<\/p>\n\n\n\n<p>Let\u2019s substitute our values of &#8216;a&#8217; and &#8216;b&#8217; into this formula:<br>-2ab = -2 * (x) * (4) = -8x<\/p>\n\n\n\n<p>The result, -8x, is exactly the same as the middle term in our original expression. This confirms that the trinomial x\u00b2 &#8211; 8x + 16 is a perfect square and fits the pattern a\u00b2 &#8211; 2ab + b\u00b2.<\/p>\n\n\n\n<p><strong>Step 3: Write the factored form.<\/strong><br>Since the trinomial matches the pattern a\u00b2 &#8211; 2ab + b\u00b2, its factored form is (a &#8211; b)\u00b2. We can now substitute our values for &#8216;a&#8217; and &#8216;b&#8217; into this factored form:<br>(a &#8211; b)\u00b2 = (x &#8211; 4)\u00b2<\/p>\n\n\n\n<p>To double check the answer, you can expand (x &#8211; 4)\u00b2:<br>(x &#8211; 4)(x &#8211; 4) = x\u00b2 &#8211; 4x &#8211; 4x + 16 = x\u00b2 &#8211; 8x + 16.<br>This matches the original expression, confirming our factorization is correct.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-1617.jpeg\" alt=\"\" class=\"wp-image-266814\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>point) Factor the perfect square trinomial x2 8x + 16.
