Solution for (2v-9)(8-v)=0 equation:


Simplifying
(2v + -9)(8 + -1v) = 0

Reorder the terms:
(-9 + 2v)(8 + -1v) = 0

Multiply (-9 + 2v) * (8 + -1v)
(-9(8 + -1v) + 2v * (8 + -1v)) = 0
((8 * -9 + -1v * -9) + 2v * (8 + -1v)) = 0
((-72 + 9v) + 2v * (8 + -1v)) = 0
(-72 + 9v + (8 * 2v + -1v * 2v)) = 0
(-72 + 9v + (16v + -2v2)) = 0

Combine like terms: 9v + 16v = 25v
(-72 + 25v + -2v2) = 0
