a=y(x+2)(x-6)

Solution for a=y(x+2)(x-6) equation:

Simplifying
a = y(x + 2)(x + -6)

Reorder the terms:
a = y(2 + x)(x + -6)

Reorder the terms:
a = y(2 + x)(-6 + x)

Multiply (2 + x) * (-6 + x)
a = y(2(-6 + x) + x(-6 + x))
a = y((-6 * 2 + x * 2) + x(-6 + x))
a = y((-12 + 2x) + x(-6 + x))
a = y(-12 + 2x + (-6 * x + x * x))
a = y(-12 + 2x + (-6x + x2))

Combine like terms: 2x + -6x = -4x
a = y(-12 + -4x + x2)
a = (-12 * y + -4x * y + x2 * y)

Reorder the terms:
a = (-4xy + x2y + -12y)
a = (-4xy + x2y + -12y)

Solving
a = -4xy + x2y + -12y

Solving for variable 'a'.

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

Simplifying
a = -4xy + x2y + -12y
