Chapter 7: Q. 95 (page 832)

In the following exercises, factor each trinomial of the form $x^{2} + b x + c$
$x^{2} - 12 - 11 x$

Short Answer

Expert verified

The factorization of $x^{2} - 12 - 11 x$ is $(x + 1) (x - 12)$

Step by step solution

Step 1. Given information

Given expression is $x^{2} - 12 - 11 x$

Step 2. Find the last terms of the binomial.

The factor of the expression:

The factor of -12	Sum of factor
2, -6	2 + (-6) = -4
3, -4	3 + (-4) = -1
1, -12	1 + (-12) = -11

Step 3. Factorization

Use $1$ and $- 12$ as the last terms of the binomial.

$x^{2} - 12 - 11 x = (x + 1) (x - 12)$

Step 4. Check

$(x + 1) (x - 12) = x^{2} + x - 12 x - 12 = x^{2} - 11 x - 12 = x^{2} - 12 - 11 x$
