Solution for Y=k(x+3)(x-4) equation: 


Simplifying
Y = k(x + 3)(x + -4)

Reorder the terms:
Y = k(3 + x)(x + -4)

Reorder the terms:
Y = k(3 + x)(-4 + x)

Multiply (3 + x) * (-4 + x)
Y = k(3(-4 + x) + x(-4 + x))
Y = k((-4 * 3 + x * 3) + x(-4 + x))
Y = k((-12 + 3x) + x(-4 + x))
Y = k(-12 + 3x + (-4 * x + x * x))
Y = k(-12 + 3x + (-4x + x2))

Combine like terms: 3x + -4x = -1x
Y = k(-12 + -1x + x2)
Y = (-12 * k + -1x * k + x2 * k)
Y = (-12k + -1kx + kx2)

Solving
Y = -12k + -1kx + kx2

Solving for variable 'Y'.

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

Simplifying
Y = -12k + -1kx + kx2
