Solution for (7x+5v-1)(4x-v)= equation: 


Simplifying
(7x + 5v + -1)(4x + -1v) = 0

Reorder the terms:
(-1 + 5v + 7x)(4x + -1v) = 0

Reorder the terms:
(-1 + 5v + 7x)(-1v + 4x) = 0

Multiply (-1 + 5v + 7x) * (-1v + 4x)
(-1(-1v + 4x) + 5v * (-1v + 4x) + 7x * (-1v + 4x)) = 0
((-1v * -1 + 4x * -1) + 5v * (-1v + 4x) + 7x * (-1v + 4x)) = 0
((1v + -4x) + 5v * (-1v + 4x) + 7x * (-1v + 4x)) = 0
(1v + -4x + (-1v * 5v + 4x * 5v) + 7x * (-1v + 4x)) = 0

Reorder the terms:
(1v + -4x + (20vx + -5v2) + 7x * (-1v + 4x)) = 0
(1v + -4x + (20vx + -5v2) + 7x * (-1v + 4x)) = 0
(1v + -4x + 20vx + -5v2 + (-1v * 7x + 4x * 7x)) = 0
(1v + -4x + 20vx + -5v2 + (-7vx + 28x2)) = 0

Reorder the terms:
(1v + 20vx + -7vx + -5v2 + -4x + 28x2) = 0

Combine like terms: 20vx + -7vx = 13vx
(1v + 13vx + -5v2 + -4x + 28x2) = 0

Solving
1v + 13vx + -5v2 + -4x + 28x2 = 0
