The solution to the equation is x = -1 and x = -7

How to determine the solution?

The equation is given as:

x^2 + 8x + 7 = 0

Expand the equation

x^2 + x + 7x + 7 = 0

Factorize the equation

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

Solve for x

x = -1 and x = -7

Hence, the solution to the equation is x = -1 and x = -7
