Solution for y=(x+8)(x-1)(x-2) equation:


Simplifying
y = (x + 8)(x + -1)(x + -2)

Reorder the terms:
y = (8 + x)(x + -1)(x + -2)

Reorder the terms:
y = (8 + x)(-1 + x)(x + -2)

Reorder the terms:
y = (8 + x)(-1 + x)(-2 + x)

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

Combine like terms: 8x + -1x = 7x
y = (-8 + 7x + x2)(-2 + x)

Multiply (-8 + 7x + x2) * (-2 + x)
y = (-8(-2 + x) + 7x * (-2 + x) + x2(-2 + x))
y = ((-2 * -8 + x * -8) + 7x * (-2 + x) + x2(-2 + x))
y = ((16 + -8x) + 7x * (-2 + x) + x2(-2 + x))
y = (16 + -8x + (-2 * 7x + x * 7x) + x2(-2 + x))
y = (16 + -8x + (-14x + 7x2) + x2(-2 + x))
y = (16 + -8x + -14x + 7x2 + (-2 * x2 + x * x2))
y = (16 + -8x + -14x + 7x2 + (-2x2 + x3))

Combine like terms: -8x + -14x = -22x
y = (16 + -22x + 7x2 + -2x2 + x3)

Combine like terms: 7x2 + -2x2 = 5x2
y = (16 + -22x + 5x2 + x3)

Solving
y = 16 + -22x + 5x2 + x3

Solving for variable 'y'.

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

Simplifying
y = 16 + -22x + 5x2 + x3
