Chapter 7: Q. 464 (page 901)

In the following exercises, factor completely. $s^{2} 鈭� 25 s + 84$

Short Answer

Expert verified

The factors of the polynomial are $(s - 4) (s - 21)$

Step by step solution

01

Step 1. Given information

$s^{2} 鈭� 25 s + 84$

02

Step 2. Factorize the polynomial

$s^{2} 鈭� 25 s + 84 = s^{2} - 21 s - 4 s + 84$

$s^{2} 鈭� 25 s + 84 = s (s - 21) - 4 (s - 21)$

$s^{2} 鈭� 25 s + 84 = (s - 21) (s - 4)$
