Solution for (v+5)(v-3)= equation:


Simplifying
(v + 5)(v + -3) = 0

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

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

Multiply (5 + v) * (-3 + v)
(5(-3 + v) + v(-3 + v)) = 0
((-3 * 5 + v * 5) + v(-3 + v)) = 0
((-15 + 5v) + v(-3 + v)) = 0
(-15 + 5v + (-3 * v + v * v)) = 0
(-15 + 5v + (-3v + v2)) = 0

Combine like terms: 5v + -3v = 2v
(-15 + 2v + v2) = 0

Solving
-15 + 2v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-5 + -1v)(3 + -1v) = 0

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 '(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

Solution

v = {-5, 3}
