y=(x-3)(x^2-x-2)

Solution for y=(x-3)(x^2-x-2) equation:

Simplifying
y = (x + -3)(x2 + -1x + -2)

Reorder the terms:
y = (-3 + x)(x2 + -1x + -2)

Reorder the terms:
y = (-3 + x)(-2 + -1x + x2)

Multiply (-3 + x) * (-2 + -1x + x2)
y = (-3(-2 + -1x + x2) + x(-2 + -1x + x2))
y = ((-2 * -3 + -1x * -3 + x2 * -3) + x(-2 + -1x + x2))
y = ((6 + 3x + -3x2) + x(-2 + -1x + x2))
y = (6 + 3x + -3x2 + (-2 * x + -1x * x + x2 * x))
y = (6 + 3x + -3x2 + (-2x + -1x2 + x3))

Reorder the terms:
y = (6 + 3x + -2x + -3x2 + -1x2 + x3)

Combine like terms: 3x + -2x = 1x
y = (6 + 1x + -3x2 + -1x2 + x3)

Combine like terms: -3x2 + -1x2 = -4x2
y = (6 + 1x + -4x2 + x3)

Solving
y = 6 + 1x + -4x2 + x3

Solving for variable 'y'.

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

Simplifying
y = 6 + 1x + -4x2 + x3
