To do this, we need to factor the quadratic polynomial.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Step 1: Look for two numbers that multiply to the constant term and add up to the coefficient of the linear term.<\/h4>\n\n\n\n<p>The polynomial is in the form ( ax^2 + bx + c ), where:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>( a = 1 ) (the coefficient of ( x^2 )),<\/li>\n\n\n\n<li>( b = -2 ) (the coefficient of ( x )),<\/li>\n\n\n\n<li>( c = -24 ) (the constant term).<\/li>\n<\/ul>\n\n\n\n<p>We need to find two numbers that multiply to ( c ) (which is ( -24 )) and add up to ( b ) (which is ( -2 )).<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The product of the two numbers should be ( -24 ), and their sum should be ( -2 ).<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Step 2: Find the pair of numbers that satisfy these conditions.<\/h4>\n\n\n\n<p>The pair of numbers that meet these criteria are <strong>-8<\/strong> and <strong>3<\/strong>, because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>( (-8) \\times 3 = -24 ),<\/li>\n\n\n\n<li>( (-8) + 3 = -2 ).<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Step 3: Factor the quadratic.<\/h4>\n\n\n\n<p>Now that we have the two numbers, we can factor the quadratic expression as follows:<br>[<br>x^2 &#8211; 2x &#8211; 24 = (x &#8211; 8)(x + 3)<br>]<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Step 4: Identify the factor.<\/h4>\n\n\n\n<p>From the factorization ( (x &#8211; 8)(x + 3) ), we can see that the polynomial is factored into two binomials: ( (x &#8211; 8) ) and ( (x + 3) ).<\/p>\n\n\n\n<p>Thus, the expression ( x + 6 ) is <strong>not<\/strong> a factor of the polynomial.
