(v-1)(v+3)=

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

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

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

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

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

Combine like terms: -1v + 3v = 2v
(-3 + 2v + v2) = 0

Solving
-3 + 2v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-3 + -1v)(1 + -1v) = 0

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

Simplifying
-3 + -1v = 0

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

Combine like terms: -3 + 3 = 0
0 + -1v = 0 + 3
-1v = 0 + 3

Combine like terms: 0 + 3 = 3
-1v = 3

Divide each side by '-1'.
v = -3

Simplifying
v = -3
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 = {-3, 1}
