Solution for (1+v)(3v-7)=0 equation:


Simplifying
(1 + v)(3v + -7) = 0

Reorder the terms:
(1 + v)(-7 + 3v) = 0

Multiply (1 + v) * (-7 + 3v)
(1(-7 + 3v) + v(-7 + 3v)) = 0
((-7 * 1 + 3v * 1) + v(-7 + 3v)) = 0
((-7 + 3v) + v(-7 + 3v)) = 0
(-7 + 3v + (-7 * v + 3v * v)) = 0
(-7 + 3v + (-7v + 3v2)) = 0

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

Solving
-7 + -4v + 3v2 = 0

Solving for variable 'v'.

Factor a trinomial.
(-1 + -1v)(7 + -3v) = 0

Subproblem 1

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

Subproblem 2

Set the factor '(7 + -3v)' equal to zero and attempt to solve: Simplifying 7 + -3v = 0 Solving 7 + -3v = 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 + -3v = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -3v = 0 + -7 -3v = 0 + -7 Combine like terms: 0 + -7 = -7 -3v = -7 Divide each side by '-3'. v = 2.333333333 Simplifying v = 2.333333333

Solution

v = {-1, 2.333333333}
