Question

What are the solutions of x^2 +6x-6= 10?

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

Answer 1

The solutions are -8 and 2. So the 4th option

Explanation:

Answer 2

x=-8 or 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

Factor

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
