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


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

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

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

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

Combine like terms: -5v + 2v = -3v
(-10 + -3v + v2) = 0

Solving
-10 + -3v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.

Subproblem 1

Set the factor '(-2 + -1v)' equal to zero and attempt to solve: Simplifying -2 + -1v = 0 Solving -2 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -1v = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1v = 0 + 2 -1v = 0 + 2 Combine like terms: 0 + 2 = 2 -1v = 2 Divide each side by '-1'. v = -2 Simplifying v = -2

Subproblem 2

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

Solution

v = {-2, 5}
