Solution for (2v+9)(4-v)=0 equation:


Simplifying
(2v + 9)(4 + -1v) = 0

Reorder the terms:
(9 + 2v)(4 + -1v) = 0

Multiply (9 + 2v) * (4 + -1v)
(9(4 + -1v) + 2v * (4 + -1v)) = 0
((4 * 9 + -1v * 9) + 2v * (4 + -1v)) = 0
((36 + -9v) + 2v * (4 + -1v)) = 0
(36 + -9v + (4 * 2v + -1v * 2v)) = 0
(36 + -9v + (8v + -2v2)) = 0

Combine like terms: -9v + 8v = -1v
(36 + -1v + -2v2) = 0
