Factor the polynomial and please show/tell steps if you can
Update:Not trying to solve for y, need to find the factorization

You probably just wanna use the quadratic formula on this one:
-b +/- sqrt(b^2 - 4ac) / 2a where
a = 27
b = -57
c = 28
so:
y = 57 +/- sqrt((-57)^2 - 4(27)(28)) / 2(28) =
57 +/- sqrt(3249 - 3024) / 56 =
57 +/- sqrt(225) / 56 =
57 +/- 15 /56 =
72/56 or 42/56
y = 3/4 or 9/7
