y=(x-6)(x-9)

Solution for y=(x-6)(x-9) equation:

Simplifying
y = (x + -6)(x + -9)

Reorder the terms:
y = (-6 + x)(x + -9)

Reorder the terms:
y = (-6 + x)(-9 + x)

Multiply (-6 + x) * (-9 + x)
y = (-6(-9 + x) + x(-9 + x))
y = ((-9 * -6 + x * -6) + x(-9 + x))
y = ((54 + -6x) + x(-9 + x))
y = (54 + -6x + (-9 * x + x * x))
y = (54 + -6x + (-9x + x2))

Combine like terms: -6x + -9x = -15x
y = (54 + -15x + x2)

Solving
y = 54 + -15x + x2

Solving for variable 'y'.

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