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

Solution for (4v-2)(5+v)= 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'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-5 + 9v + 2v2) = 0

Factor a trinomial.
2((-5 + -1v)(1 + -2v)) = 0

Ignore the factor 2.
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}
