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

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

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

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

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

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

Combine like terms: 3x + -1x = 2x
y = 2(-3 + 2x + x2)
y = (-3 * 2 + 2x * 2 + x2 * 2)
y = (-6 + 4x + 2x2)

Solving
y = -6 + 4x + 2x2

Solving for variable 'y'.

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

Simplifying
y = -6 + 4x + 2x2
