Solution for (v-9)(v+3)=0 equation:


Simplifying
(v + -9)(v + 3) = 0

Reorder the terms:
(-9 + v)(v + 3) = 0

Reorder the terms:
(-9 + v)(3 + v) = 0

Multiply (-9 + v) * (3 + v)
(-9(3 + v) + v(3 + v)) = 0
((3 * -9 + v * -9) + v(3 + v)) = 0
((-27 + -9v) + v(3 + v)) = 0
(-27 + -9v + (3 * v + v * v)) = 0
(-27 + -9v + (3v + v2)) = 0

Combine like terms: -9v + 3v = -6v
(-27 + -6v + v2) = 0

Solving
-27 + -6v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-3 + -1v)(9 + -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 '(9 + -1v)' equal to zero and attempt to solve: Simplifying 9 + -1v = 0 Solving 9 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1v = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1v = 0 + -9 -1v = 0 + -9 Combine like terms: 0 + -9 = -9 -1v = -9 Divide each side by '-1'. v = 9 Simplifying v = 9

Solution

v = {-3, 9}
