Solution for v(x)=(2x+5)(2x+7)(x+4) equation:


Simplifying
v(x) = (2x + 5)(2x + 7)(x + 4)

Multiply v * x
vx = (2x + 5)(2x + 7)(x + 4)

Reorder the terms:
vx = (5 + 2x)(2x + 7)(x + 4)

Reorder the terms:
vx = (5 + 2x)(7 + 2x)(x + 4)

Reorder the terms:
vx = (5 + 2x)(7 + 2x)(4 + x)

Multiply (5 + 2x) * (7 + 2x)
vx = (5(7 + 2x) + 2x * (7 + 2x))(4 + x)
vx = ((7 * 5 + 2x * 5) + 2x * (7 + 2x))(4 + x)
vx = ((35 + 10x) + 2x * (7 + 2x))(4 + x)
vx = (35 + 10x + (7 * 2x + 2x * 2x))(4 + x)
vx = (35 + 10x + (14x + 4x2))(4 + x)

Combine like terms: 10x + 14x = 24x
vx = (35 + 24x + 4x2)(4 + x)

Multiply (35 + 24x + 4x2) * (4 + x)
vx = (35(4 + x) + 24x * (4 + x) + 4x2 * (4 + x))
vx = ((4 * 35 + x * 35) + 24x * (4 + x) + 4x2 * (4 + x))
vx = ((140 + 35x) + 24x * (4 + x) + 4x2 * (4 + x))
vx = (140 + 35x + (4 * 24x + x * 24x) + 4x2 * (4 + x))
vx = (140 + 35x + (96x + 24x2) + 4x2 * (4 + x))
vx = (140 + 35x + 96x + 24x2 + (4 * 4x2 + x * 4x2))
vx = (140 + 35x + 96x + 24x2 + (16x2 + 4x3))

Combine like terms: 35x + 96x = 131x
vx = (140 + 131x + 24x2 + 16x2 + 4x3)

Combine like terms: 24x2 + 16x2 = 40x2
vx = (140 + 131x + 40x2 + 4x3)

Solving
vx = 140 + 131x + 40x2 + 4x3

Solving for variable 'v'.

Move all terms containing v to the left, all other terms to the right.

Divide each side by 'x'.
v = 140x-1 + 131 + 40x + 4x2

Simplifying
v = 140x-1 + 131 + 40x + 4x2

Reorder the terms:
v = 131 + 140x-1 + 40x + 4x2
