What are the solutions of the equation (x + 2)2 – 2(x + 2) – 15 = 0? use u substitution to solve. x = –7 and x = 1 x = –5 and x = 3 x = –3 and x = 5 x = –1 and x = 7

B.) x = –5 and x = 3

The given equation is

So we will get

Factoring the left side

Solving both equations for u

Performing back substitution

And that's the required solutions .
