Solution for product(9x-4)(5x+5)= equation:


Simplifying
product(9x + -4)(5x + 5) = 0

Reorder the terms:
cdoprtu(-4 + 9x)(5x + 5) = 0

Reorder the terms:
cdoprtu(-4 + 9x)(5 + 5x) = 0

Multiply (-4 + 9x) * (5 + 5x)
cdoprtu(-4(5 + 5x) + 9x * (5 + 5x)) = 0
cdoprtu((5 * -4 + 5x * -4) + 9x * (5 + 5x)) = 0
cdoprtu((-20 + -20x) + 9x * (5 + 5x)) = 0
cdoprtu(-20 + -20x + (5 * 9x + 5x * 9x)) = 0
cdoprtu(-20 + -20x + (45x + 45x2)) = 0

Combine like terms: -20x + 45x = 25x
cdoprtu(-20 + 25x + 45x2) = 0
(-20 * cdoprtu + 25x * cdoprtu + 45x2 * cdoprtu) = 0
(-20cdoprtu + 25cdoprtux + 45cdoprtux2) = 0

Solving
-20cdoprtu + 25cdoprtux + 45cdoprtux2 = 0
