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

Reorder the terms:
(5 + -1v)(-9 + 5v) = 0

Multiply (5 + -1v) * (-9 + 5v)
(5(-9 + 5v) + -1v * (-9 + 5v)) = 0
((-9 * 5 + 5v * 5) + -1v * (-9 + 5v)) = 0
((-45 + 25v) + -1v * (-9 + 5v)) = 0
(-45 + 25v + (-9 * -1v + 5v * -1v)) = 0
(-45 + 25v + (9v + -5v2)) = 0

Combine like terms: 25v + 9v = 34v
(-45 + 34v + -5v2) = 0
