Find the value of c that completes the square. u^2+22u+c

A. 11

B. 22

C. 112

D. 121

the value of c that completes the square is 121

(u + 11) (u + 11)

u^2 + 11u + 11u + 121

u^2 + 22u + 121

The answer to your question is letter D.

Step-by-step explanation:

Polynomial u² + 22u + c = 0

Process

1. - Equal to zero

u² + 22u = 0

2. - Divide 22 by 2

22/2 = 1

3. - Place 11² as a third term

u² + 22u + (11) ²

4. - Simplify

u² + 22u + 121
