Simplifying
(4v + 9)(5 + -1v) = 0

Reorder the terms:
(9 + 4v)(5 + -1v) = 0

Multiply (9 + 4v) * (5 + -1v)
(9(5 + -1v) + 4v * (5 + -1v)) = 0
((5 * 9 + -1v * 9) + 4v * (5 + -1v)) = 0
((45 + -9v) + 4v * (5 + -1v)) = 0
(45 + -9v + (5 * 4v + -1v * 4v)) = 0
(45 + -9v + (20v + -4v2)) = 0

Combine like terms: -9v + 20v = 11v
(45 + 11v + -4v2) = 0
