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 = -12v
(27 + -12v + v2) = 0

Solving
27 + -12v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.

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}
