Solution for (5v-1)(2-v)=0 equation:


Simplifying
(5v + -1)(2 + -1v) = 0

Reorder the terms:
(-1 + 5v)(2 + -1v) = 0

Multiply (-1 + 5v) * (2 + -1v)
(-1(2 + -1v) + 5v * (2 + -1v)) = 0
((2 * -1 + -1v * -1) + 5v * (2 + -1v)) = 0
((-2 + 1v) + 5v * (2 + -1v)) = 0
(-2 + 1v + (2 * 5v + -1v * 5v)) = 0
(-2 + 1v + (10v + -5v2)) = 0

Combine like terms: 1v + 10v = 11v
(-2 + 11v + -5v2) = 0

Solving
-2 + 11v + -5v2 = 0

Solving for variable 'v'.

Factor a trinomial.

Subproblem 1

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

Subproblem 2

Set the factor '(1 + -5v)' equal to zero and attempt to solve: Simplifying 1 + -5v = 0 Solving 1 + -5v = 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 + -5v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -5v = 0 + -1 -5v = 0 + -1 Combine like terms: 0 + -1 = -1 -5v = -1 Divide each side by '-5'. v = 0.2 Simplifying v = 0.2

Solution

v = {2, 0.2}
