See full solution process below:

First, we need to factor the quadratic equation:

$(x - 7)(x + 1)$

Now we need to solve each term for $0$ :

Solution 1)

$x - 7 = 0$

$x - 7 + 7 = 0 + 7$

$x - 0 = 7$

$x = 7$

Solution 2)

$x + 1 = 0$

$x + 1 - 1 = 0 - 1$

$x + 0 = -1$

$x = -1$

The solution is:

$x = 7$ and $x = -1$
