Simplifying
(2 + -1v)(5v + 4) = 0

Reorder the terms:
(2 + -1v)(4 + 5v) = 0

Multiply (2 + -1v) * (4 + 5v)
(2(4 + 5v) + -1v * (4 + 5v)) = 0
((4 * 2 + 5v * 2) + -1v * (4 + 5v)) = 0
((8 + 10v) + -1v * (4 + 5v)) = 0
(8 + 10v + (4 * -1v + 5v * -1v)) = 0
(8 + 10v + (-4v + -5v2)) = 0

Combine like terms: 10v + -4v = 6v
(8 + 6v + -5v2) = 0
