Chapter 11: Q 6.19 TI (page 1069)

Factor $u^{2} - 9 u + 18$

Short Answer

Expert verified

The factored form is $(u - 3) (u - 6)$

Step by step solution

Given information

Given the polynomial, $u^{2} - 9 u + 18$

Writing as parentheses

The polynomial can be written as $(u) (u)$ . Now creating the table

Factors of $18$	Sum of factors
$1, 18$	$1 + 18 = 19$
$2, 9$	$2 + 9 = 11$
$- 3, - 6$	$- 3 - 6 = - 9$

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

Here

$m, n = - 3, - 6 m + n = - 9 m n = 18$

Substitute the values and form the factored polynomial

The factored form is $(u - 3) (u - 6)$
