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


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

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

Multiply (9 + -1v) * (-2 + 4v)
(9(-2 + 4v) + -1v * (-2 + 4v)) = 0
((-2 * 9 + 4v * 9) + -1v * (-2 + 4v)) = 0
((-18 + 36v) + -1v * (-2 + 4v)) = 0
(-18 + 36v + (-2 * -1v + 4v * -1v)) = 0
(-18 + 36v + (2v + -4v2)) = 0

Combine like terms: 36v + 2v = 38v
(-18 + 38v + -4v2) = 0

Solving
-18 + 38v + -4v2 = 0

Solving for variable 'v'.

Factor out the Greatest Common Factor (GCF), '2'.

Subproblem 1

Set the factor '(-9 + v)' equal to zero and attempt to solve: Simplifying -9 + v = 0 Solving -9 + v = 0 Move all terms containing v to the left, all other terms to the right. Add '9' to each side of the equation. -9 + 9 + v = 0 + 9 Combine like terms: -9 + 9 = 0 0 + v = 0 + 9 v = 0 + 9 Combine like terms: 0 + 9 = 9 v = 9 Simplifying v = 9

Subproblem 2

Set the factor '(1 + -2v)' equal to zero and attempt to solve: Simplifying 1 + -2v = 0 Solving 1 + -2v = 0 Move all terms containing v to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -2v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2v = 0 + -1 -2v = 0 + -1 Combine like terms: 0 + -1 = -1 -2v = -1 Divide each side by '-2'. v = 0.5 Simplifying v = 0.5

Solution

v = {9, 0.5}
