Solution for y=(x+1)(3x-4)(x-3) equation:


Simplifying
y = (x + 1)(3x + -4)(x + -3)

Reorder the terms:
y = (1 + x)(3x + -4)(x + -3)

Reorder the terms:
y = (1 + x)(-4 + 3x)(x + -3)

Reorder the terms:
y = (1 + x)(-4 + 3x)(-3 + x)

Multiply (1 + x) * (-4 + 3x)
y = (1(-4 + 3x) + x(-4 + 3x))(-3 + x)
y = ((-4 * 1 + 3x * 1) + x(-4 + 3x))(-3 + x)
y = ((-4 + 3x) + x(-4 + 3x))(-3 + x)
y = (-4 + 3x + (-4 * x + 3x * x))(-3 + x)
y = (-4 + 3x + (-4x + 3x2))(-3 + x)

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

Multiply (-4 + -1x + 3x2) * (-3 + x)
y = (-4(-3 + x) + -1x * (-3 + x) + 3x2 * (-3 + x))
y = ((-3 * -4 + x * -4) + -1x * (-3 + x) + 3x2 * (-3 + x))
y = ((12 + -4x) + -1x * (-3 + x) + 3x2 * (-3 + x))
y = (12 + -4x + (-3 * -1x + x * -1x) + 3x2 * (-3 + x))
y = (12 + -4x + (3x + -1x2) + 3x2 * (-3 + x))
y = (12 + -4x + 3x + -1x2 + (-3 * 3x2 + x * 3x2))
y = (12 + -4x + 3x + -1x2 + (-9x2 + 3x3))

Combine like terms: -4x + 3x = -1x
y = (12 + -1x + -1x2 + -9x2 + 3x3)

Combine like terms: -1x2 + -9x2 = -10x2
y = (12 + -1x + -10x2 + 3x3)

Solving
y = 12 + -1x + -10x2 + 3x3

Solving for variable 'y'.

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

Simplifying
y = 12 + -1x + -10x2 + 3x3
