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


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

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

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

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

Combine like terms: -7v + 4v = -3v
(-28 + -3v + v2) = 0

Solving
-28 + -3v + v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-4 + -1v)(7 + -1v) = 0

Subproblem 1

Set the factor '(-4 + -1v)' equal to zero and attempt to solve: Simplifying -4 + -1v = 0 Solving -4 + -1v = 0 Move all terms containing v to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + -1v = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -1v = 0 + 4 -1v = 0 + 4 Combine like terms: 0 + 4 = 4 -1v = 4 Divide each side by '-1'. v = -4 Simplifying v = -4

Subproblem 2

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

Solution

v = {-4, 7}
