-5(-7 + v)(-9 + -1v) = 0

Multiply (-7 + v) * (-9 + -1v)
-5(-7(-9 + -1v) + v(-9 + -1v)) = 0
-5((-9 * -7 + -1v * -7) + v(-9 + -1v)) = 0
-5((63 + 7v) + v(-9 + -1v)) = 0
-5(63 + 7v + (-9 * v + -1v * v)) = 0
-5(63 + 7v + (-9v + -1v2)) = 0

Combine like terms: 7v + -9v = -2v
-5(63 + -2v + -1v2) = 0
(63 * -5 + -2v * -5 + -1v2 * -5) = 0
(-315 + 10v + 5v2) = 0
