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

Solution for y=(x+1)(x-2)(x-3) equation:

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

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

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

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

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

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

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

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

Combine like terms: -1x2 + -3x2 = -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
