(7 + -1x + (-7 * x + x * x))(5 + x) = 0
(7 + -1x + (-7x + x2))(5 + x) = 0

Combine like terms: -1x + -7x = -8x
(7 + -8x + x2)(5 + x) = 0

Multiply (7 + -8x + x2) * (5 + x)
(7(5 + x) + -8x * (5 + x) + x2(5 + x)) = 0
((5 * 7 + x * 7) + -8x * (5 + x) + x2(5 + x)) = 0
((35 + 7x) + -8x * (5 + x) + x2(5 + x)) = 0
(35 + 7x + (5 * -8x + x * -8x) + x2(5 + x)) = 0
(35 + 7x + (-40x + -8x2) + x2(5 + x)) = 0
(35 + 7x + -40x + -8x2 + (5 * x2 + x * x2)) = 0
(35 + 7x + -40x + -8x2 + (5x2 + x3)) = 0

Combine like terms: 7x + -40x = -33x
(35 + -33x + -8x2 + 5x2 + x3) = 0
