Solution for y=x(4x-1)(2x-7) equation: 


Simplifying
y = x(4x + -1)(2x + -7)

Reorder the terms:
y = x(-1 + 4x)(2x + -7)

Reorder the terms:
y = x(-1 + 4x)(-7 + 2x)

Multiply (-1 + 4x) * (-7 + 2x)
y = x(-1(-7 + 2x) + 4x * (-7 + 2x))
y = x((-7 * -1 + 2x * -1) + 4x * (-7 + 2x))
y = x((7 + -2x) + 4x * (-7 + 2x))
y = x(7 + -2x + (-7 * 4x + 2x * 4x))
y = x(7 + -2x + (-28x + 8x2))

Combine like terms: -2x + -28x = -30x
y = x(7 + -30x + 8x2)
y = (7 * x + -30x * x + 8x2 * x)
y = (7x + -30x2 + 8x3)

Solving
y = 7x + -30x2 + 8x3

Solving for variable 'y'.

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

Simplifying
y = 7x + -30x2 + 8x3
