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


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

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

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

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

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

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

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

Combine like terms: -3x + -4x = -7x
y = (-6 + -7x + -2x2 + 2x2 + x3)

Combine like terms: -2x2 + 2x2 = 0
y = (-6 + -7x + 0 + x3)
y = (-6 + -7x + x3)

Solving
y = -6 + -7x + x3

Solving for variable 'y'.

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

Simplifying
y = -6 + -7x + x3
