Solution for -4(v+9)(-v-1)=0 equation:


Simplifying
-4(v + 9)(-1v + -1) = 0

Reorder the terms:
-4(9 + v)(-1v + -1) = 0

Reorder the terms:
-4(9 + v)(-1 + -1v) = 0

Multiply (9 + v) * (-1 + -1v)
-4(9(-1 + -1v) + v(-1 + -1v)) = 0
-4((-1 * 9 + -1v * 9) + v(-1 + -1v)) = 0
-4((-9 + -9v) + v(-1 + -1v)) = 0
-4(-9 + -9v + (-1 * v + -1v * v)) = 0
-4(-9 + -9v + (-1v + -1v2)) = 0

Combine like terms: -9v + -1v = -10v
-4(-9 + -10v + -1v2) = 0
(-9 * -4 + -10v * -4 + -1v2 * -4) = 0
(36 + 40v + 4v2) = 0

Solving
36 + 40v + 4v2 = 0

Solving for variable 'v'.

Subproblem 1

Set the factor '(9 + v)' equal to zero and attempt to solve: Simplifying 9 + v = 0 Solving 9 + v = 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 + v = 0 + -9 Combine like terms: 9 + -9 = 0 0 + v = 0 + -9 v = 0 + -9 Combine like terms: 0 + -9 = -9 v = -9 Simplifying v = -9

Subproblem 2

Set the factor '(1 + v)' equal to zero and attempt to solve: Simplifying 1 + v = 0 Solving 1 + v = 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 + v = 0 + -1 Combine like terms: 1 + -1 = 0 0 + v = 0 + -1 v = 0 + -1 Combine like terms: 0 + -1 = -1 v = -1 Simplifying v = -1

Solution

v = {-9, -1}
