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


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

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

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

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

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

Combine like terms: 1x + -4x = -3x
y = (-2 + -3x + 2x2)(-2 + x)

Multiply (-2 + -3x + 2x2) * (-2 + x)
y = (-2(-2 + x) + -3x * (-2 + x) + 2x2 * (-2 + x))
y = ((-2 * -2 + x * -2) + -3x * (-2 + x) + 2x2 * (-2 + x))
y = ((4 + -2x) + -3x * (-2 + x) + 2x2 * (-2 + x))
y = (4 + -2x + (-2 * -3x + x * -3x) + 2x2 * (-2 + x))
y = (4 + -2x + (6x + -3x2) + 2x2 * (-2 + x))
y = (4 + -2x + 6x + -3x2 + (-2 * 2x2 + x * 2x2))
y = (4 + -2x + 6x + -3x2 + (-4x2 + 2x3))

Combine like terms: -2x + 6x = 4x
y = (4 + 4x + -3x2 + -4x2 + 2x3)

Combine like terms: -3x2 + -4x2 = -7x2
y = (4 + 4x + -7x2 + 2x3)

Solving
y = 4 + 4x + -7x2 + 2x3

Solving for variable 'y'.

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

Simplifying
y = 4 + 4x + -7x2 + 2x3
