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#
