Solve the equation by completing the square. round to the nearest hundredth if necessary. x^2+2x=8

x² + 2x = 8

x² + 2x - 8 = 8 - 8

x² + 2x - 8 = 0

x² - 2x + 4x - 8 = 0

x (x) - x (2) + 4 (x) - 4 (2) = 0

x (x - 2) + 4 (x - 2) = 0

(x + 4) (x - 2) = 0

x + 4 = 0 U x - 2 = 0

- 4 - 4 + 2 + 2

x = - 4 x = 2
