Question

Solve the equation.

x2 − 6x − 7 = 0

Answer 1

Answer:

x = 7 and x = -1

Step-by-step explanation:

Step 1:  Factor

x^2 - 6x - 7 = 0

(x - 7)(x + 1) = 0

Step 2:  Solve for x

(x - 7)(x + 1) = 0

x - 7 = 0 and x + 1 = 0

x - 7 + 7 = 0 + 7 and x + 1 - 1 = 0 - 1

x = 7 and x = -1

Answer:  x = 7 and x = -1
