(-15 + 3x + (-5 * x + x * x))(7 + x) = 0
(-15 + 3x + (-5x + x2))(7 + x) = 0

Combine like terms: 3x + -5x = -2x
(-15 + -2x + x2)(7 + x) = 0

Multiply (-15 + -2x + x2) * (7 + x)
(-15(7 + x) + -2x * (7 + x) + x2(7 + x)) = 0
((7 * -15 + x * -15) + -2x * (7 + x) + x2(7 + x)) = 0
((-105 + -15x) + -2x * (7 + x) + x2(7 + x)) = 0
(-105 + -15x + (7 * -2x + x * -2x) + x2(7 + x)) = 0
(-105 + -15x + (-14x + -2x2) + x2(7 + x)) = 0
(-105 + -15x + -14x + -2x2 + (7 * x2 + x * x2)) = 0
(-105 + -15x + -14x + -2x2 + (7x2 + x3)) = 0
