Chapter 6: Q 6.22TI (page 577)

Factor $- 7 n + 12 + n^{2}$

Short Answer

Expert verified

The factored form is $(n - 3) (n - 4)$

Step by step solution

Given information

Given the polynomial $- 7 n + 12 + n^{2}$

Arranging in decreasing order

The polynomial in decreasing order is , $n^{2} - 7 n + 12$

Writing as parentheses

The polynomial in parentheses is $(n) (n)$ . The table is

Factors of $12$	Sum of factors
$1, 12$	$1 + 12 = 13$
$2, 6$	$2 + 6 = 8$
$- 3, - 4$	$- 3 - 4 = - 7$

Use m,n as last terms of factors and form the factored polynomial

Here

$m, n = - 3, - 4 m + n = - 7 m \times n = 12$

Substitute the values and form the factored form

The factored form is $(n - 3) (n - 4)$
