Please help

Answer 1

I found this on an app I used it by completing the square but it didn't show this

Answer 2

Answer:  A) (x + 3)^2 + 6

Step-by-step explanation:

x^2 + 6x + 15

Subtract 15 from both sides of the equation.

x^2 + 6x = -15

Complete the equation and add to both sides. Since (6 = 3 + 3), (3 x 3 = 9)                

x^2 + 6x + 9 = -15 + 9

Simplify

(x + 3)^2 = -6

Add 6 to both sides of the equation

(x + 3)^2 + 6
