Question

what is the intermediate step in the form (x+a)^2=b as the result of completing the square for the following equation? 2x^2 + 28x = -226

Answer 1

Explanation:

2x² + 28x = -226

Divide both sides by 2.

x² + 14x = -113

Add (14/2)² = 49 to both sides.

x² + 14x + 49 = -113 + 49

x² + 14x + 49 = -64

Factor.

(x + 7)² = -64
