Solution for y=(q-a)(q+b) equation: 


Simplifying
y = (q + -1a)(q + b)

Reorder the terms:
y = (-1a + q)(q + b)

Reorder the terms:
y = (-1a + q)(b + q)

Multiply (-1a + q) * (b + q)
y = (-1a * (b + q) + q(b + q))
y = ((b * -1a + q * -1a) + q(b + q))
y = ((-1ab + -1aq) + q(b + q))
y = (-1ab + -1aq + (b * q + q * q))
y = (-1ab + -1aq + (bq + q2))
y = (-1ab + -1aq + bq + q2)

Solving
y = -1ab + -1aq + bq + q2

Solving for variable 'y'.

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