Question

What are the solutions of x2 +6x-6= 10?

O x=-11 or x=1
O X=-11 or X=-1
O X=-8 or X=-2
O X=-8 or X= 2

Answer 1

Answer:D

Explanation:

Answer 2

x= -8 x=2

Explanation:

x^2 +6x-6= 10

Subtract 10 from each side

x^2 +6x-6-10= 10-10

x^2 +6x-16 = 0

What 2 number multiply to -16 and add to 6

8 * -2 = -16

8 -2 = 6

(x+8) (x-2)=0

Using the zero product property

x+8=0 x-2=0

x= -8 x=2
