Solution for (7+v)(4v-6)=0 equation:


Simplifying
(7 + v)(4v + -6) = 0

Reorder the terms:
(7 + v)(-6 + 4v) = 0

Multiply (7 + v) * (-6 + 4v)
(7(-6 + 4v) + v(-6 + 4v)) = 0
((-6 * 7 + 4v * 7) + v(-6 + 4v)) = 0
((-42 + 28v) + v(-6 + 4v)) = 0
(-42 + 28v + (-6 * v + 4v * v)) = 0
(-42 + 28v + (-6v + 4v2)) = 0

Combine like terms: 28v + -6v = 22v
(-42 + 22v + 4v2) = 0

Solving
-42 + 22v + 4v2 = 0

Solving for variable 'v'.

Factor out the Greatest Common Factor (GCF), '2'.
2(-21 + 11v + 2v2) = 0

Subproblem 1

Set the factor '(-7 + -1v)' equal to zero and attempt to solve: Simplifying -7 + -1v = 0 Solving -7 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1v = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1v = 0 + 7 -1v = 0 + 7 Combine like terms: 0 + 7 = 7 -1v = 7 Divide each side by '-1'. v = -7 Simplifying v = -7

Subproblem 2

Set the factor '(3 + -2v)' equal to zero and attempt to solve: Simplifying 3 + -2v = 0 Solving 3 + -2v = 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 + -2v = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -2v = 0 + -3 -2v = 0 + -3 Combine like terms: 0 + -3 = -3 -2v = -3 Divide each side by '-2'. v = 1.5 Simplifying v = 1.5

Solution

v = {-7, 1.5}
