That equation factorizes as (5x-4)(5x-4), so if the original expression is the area, then one of those two identical factors must represent the side.
so is (5x-4) the actual answer or do I have to factor it further
You won't be able to factor it further, so yes: that's the answer.
thank you
wrong that equals o 25x^2+20x+32
