Solution for (r-8)(r+4)=product equation:


Simplifying
(r + -8)(r + 4) = product

Reorder the terms:
(-8 + r)(r + 4) = product

Reorder the terms:
(-8 + r)(4 + r) = product

Multiply (-8 + r) * (4 + r)
(-8(4 + r) + r(4 + r)) = product
((4 * -8 + r * -8) + r(4 + r)) = product
((-32 + -8r) + r(4 + r)) = product
(-32 + -8r + (4 * r + r * r)) = product
(-32 + -8r + (4r + r2)) = product
