Chapter 7: Q 130. (page 833)

Consecutive integers Deshawn is thinking of two
consecutive integers whose product is $182$ .
The trinomial $x^{2} + x - 182$ describes how these numbers are related. Factor the trinomial.

Short Answer

Expert verified

The factorization of $x^{2} + x - 182$ is, $(x - 13) (x + 14)$ .

Step by step solution

Step 1. Given information

Given expression is $x^{2} + x - 182$ .

Step 2. Find the last terms of the binomials

Write the factors as two binomials with the first terms $x$ .

$(x) (x)$

Find the numbers that multiply $- 182$ and add to $1$ .

Factors of -182	Sum of factors
-1, 182	-1 + 182 = 181
-2, 91	-2 + 91 = 89
-7, 26	-7 + 26 = 19
-13, 14	-13 + 14 = 1*
-14, 13	-14 + 13 = -1
-26, 7	-26 + 7 = -19
-91, 2	-91 + 2 = -89
-182, 1	-182 + 1 = -181

Step 3. Factorization

use $- 13$ and $14$ as the last terms of the binomials.

$x^{2} + x - 182 = (x - 13) (x + 14)$

Step 4. Check

$(x - 13) (x + 14) = x^{2} + 14 x - 13 x - 182 = x^{2} + x - 182$
