(v-1)(4v+3)=0

Solution for (v-1)(4v+3)=0 equation:

Simplifying
(v + -1)(4v + 3) = 0

Reorder the terms:
(-1 + v)(4v + 3) = 0

Reorder the terms:
(-1 + v)(3 + 4v) = 0

Multiply (-1 + v) * (3 + 4v)
(-1(3 + 4v) + v(3 + 4v)) = 0
((3 * -1 + 4v * -1) + v(3 + 4v)) = 0
((-3 + -4v) + v(3 + 4v)) = 0
(-3 + -4v + (3 * v + 4v * v)) = 0
(-3 + -4v + (3v + 4v2)) = 0

Combine like terms: -4v + 3v = -1v
(-3 + -1v + 4v2) = 0

Solving
-3 + -1v + 4v2 = 0

Solving for variable 'v'.

Factor a trinomial.

Subproblem 1
Set the factor '(-3 + -4v)' equal to zero and attempt to solve:

Simplifying
-3 + -4v = 0

Solving
-3 + -4v = 0

Move all terms containing v to the left, all other terms to the right.

Add '3' to each side of the equation.
-3 + 3 + -4v = 0 + 3

Combine like terms: -3 + 3 = 0
0 + -4v = 0 + 3
-4v = 0 + 3

Combine like terms: 0 + 3 = 3
-4v = 3

Divide each side by '-4'.
v = -0.75

Simplifying
v = -0.75
Subproblem 2
Set the factor '(1 + -1v)' equal to zero and attempt to solve:

Simplifying
1 + -1v = 0

Solving
1 + -1v = 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 + -1v = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -1v = 0 + -1
-1v = 0 + -1

Combine like terms: 0 + -1 = -1
-1v = -1

Divide each side by '-1'.
v = 1

Simplifying
v = 1
Solution
v = {-0.75, 1}
