Solution for y=2(x+3)(x-4) equation: 


Simplifying
y = 2(x + 3)(x + -4)

Reorder the terms:
y = 2(3 + x)(x + -4)

Reorder the terms:
y = 2(3 + x)(-4 + x)

Multiply (3 + x) * (-4 + x)
y = 2(3(-4 + x) + x(-4 + x))
y = 2((-4 * 3 + x * 3) + x(-4 + x))
y = 2((-12 + 3x) + x(-4 + x))
y = 2(-12 + 3x + (-4 * x + x * x))
y = 2(-12 + 3x + (-4x + x2))

Combine like terms: 3x + -4x = -1x
y = 2(-12 + -1x + x2)
y = (-12 * 2 + -1x * 2 + x2 * 2)
y = (-24 + -2x + 2x2)

Solving
y = -24 + -2x + 2x2

Solving for variable 'y'.
