Solution for (8-v)(2v-1)=0 equation:


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

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

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

Combine like terms: 16v + 1v = 17v
(-8 + 17v + -2v2) = 0

Solving
-8 + 17v + -2v2 = 0

Solving for variable 'v'.

Factor a trinomial.
