y=3(x-5)(x-6)

Solution for y=3(x-5)(x-6) equation:

Simplifying
y = 3(x + -5)(x + -6)

Reorder the terms:
y = 3(-5 + x)(x + -6)

Reorder the terms:
y = 3(-5 + x)(-6 + x)

Multiply (-5 + x) * (-6 + x)
y = 3(-5(-6 + x) + x(-6 + x))
y = 3((-6 * -5 + x * -5) + x(-6 + x))
y = 3((30 + -5x) + x(-6 + x))
y = 3(30 + -5x + (-6 * x + x * x))
y = 3(30 + -5x + (-6x + x2))

Combine like terms: -5x + -6x = -11x
y = 3(30 + -11x + x2)
y = (30 * 3 + -11x * 3 + x2 * 3)
y = (90 + -33x + 3x2)

Solving
y = 90 + -33x + 3x2

Solving for variable 'y'.

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

Simplifying
