Question

Use completing the square to solve for in the equation . x = –1 or 15 x = 1 or 7

Answer 1

x^2 + bx + c = 0

Given your equation:

1. x = -1 or 15x = 1 or 7

Let’s focus on the second equation:

15x = 1 or 7

To solve for x in this equation, you need to isolate x. First, divide both sides by 15:

x = 1/15 or 7/15

So, the correct solutions for x are:

1. x = -1
2. x = 1/15 or 7/15
