Solution for (4-v)(v-8)=0 equation:


Simplifying
(4 + -1v)(v + -8) = 0

Reorder the terms:
(4 + -1v)(-8 + v) = 0

Multiply (4 + -1v) * (-8 + v)
(4(-8 + v) + -1v * (-8 + v)) = 0
((-8 * 4 + v * 4) + -1v * (-8 + v)) = 0
((-32 + 4v) + -1v * (-8 + v)) = 0
(-32 + 4v + (-8 * -1v + v * -1v)) = 0
(-32 + 4v + (8v + -1v2)) = 0

Combine like terms: 4v + 8v = 12v
(-32 + 12v + -1v2) = 0

Solving
-32 + 12v + -1v2 = 0

Solving for variable 'v'.

Factor a trinomial.
