Question

Complete the square. Fill in the number that makes the polynomial a perfect-square quadratic. q2 − 28q +

Answer 1

196

Explanation:

On a separate piece of paper do these steps.

Divide - 28 by 2 which gives - 14

square - 14 giving you (-14)^2 = 196

Write that after the plus sign.

q^2 - 28q + 196

This gives a perfect square quadratic.

(q - 14)^2 when expanded gives q^2 - 28q + 196
