What are the solutions of x2+6x-6-10 a) x=-11 or x=1
b) x=-11 or x=-1
c) x=-8 or x=-2
d) x=-8 or x=2

D. x = -8 or x = 2

Step-by-step explanation:

x² + 6x - 6 -10 = 0

⇔ x² + 6x - 16 = 0

⇔ x² + 8x - 2x - 16 = 0

⇔ x(x + 8) - 2(x +8) = 0

⇔ (x - 2)(x + 8) = 0

⇔ x - 2 = 0 or x + 8 = 0

⇔ x = 2 or x = -8
