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

x = - 8 or x = - 2
x = - 8 or x = 2
x = 1 or x = - 7
x = - 1 or x = 7

x=- 8 or x=2

Step-by-step explanation:

1. To solve this problem you can applly the quadratic formula, which is shown below:

2. The quadratic  equation is:

3. Then:

a=1

b=6

c=-16

4. Therefore, when you substitute these values into the quadratic formula, you obtain the following result:
