Solution for (4v-2)(5+v)=0 equation:


Simplifying
(4v + -2)(5 + v) = 0

Reorder the terms:
(-2 + 4v)(5 + v) = 0

Multiply (-2 + 4v) * (5 + v)
(-2(5 + v) + 4v * (5 + v)) = 0
((5 * -2 + v * -2) + 4v * (5 + v)) = 0
((-10 + -2v) + 4v * (5 + v)) = 0
(-10 + -2v + (5 * 4v + v * 4v)) = 0
(-10 + -2v + (20v + 4v2)) = 0

Combine like terms: -2v + 20v = 18v
(-10 + 18v + 4v2) = 0

Solving
-10 + 18v + 4v2 = 0

Solving for variable 'v'.

Subproblem 1

Set the factor '(-5 + -1v)' equal to zero and attempt to solve: Simplifying -5 + -1v = 0 Solving -5 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + -1v = 0 + 5 Combine like terms: -5 + 5 = 0 0 + -1v = 0 + 5 -1v = 0 + 5 Combine like terms: 0 + 5 = 5 -1v = 5 Divide each side by '-1'. v = -5 Simplifying v = -5

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 = {-5, 0.5}
