Find the other factor for the trinomial 28x²+57x+27 if one factor is (4x+3)
------------------
If 4x+3 is a factor, then the other factor has to be 7x + 9
=====================
Does (4x+3)*(7x+9) = 28x^2 + 57x + 27?
It does.
======================
I have no idea what you're doing wrong, other than not having the given factor in your product.
