Solve for x. simplify completely. x^2+4x+4=8

The first thing we need to do is get ZERO on the opposite side of the quadratic expression. We can do this by subtracting 8 from both sides. You will get this:

x^2 + 4x - 4 = 0

Now that we have a quadratic expression equaling ZERO, we need to use the quadratic formula: x= 

a= coefficient of x^2
b= coefficient of x
c= last term



The final answer would be x = 

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
