Question

Rewrite the equation by completing the square. x^{2} +7 x +12 = 0

Answer 1

Answer:

(x+7/2)^2 - 1/4 = 0

Step-by-step explanation:

x^2 + 7x + 12 = 0

x^2 + 7x = -12

x^2 + 7x + (7/2)^2 = -12

x^2 + 7x + 49/4 = -12  + 49/4

x^2 + 7x + 49/4 = 1/4

(x + 7/2)^2 = 1/4

(x + 7/2)^2 - 1/4 = 0
