Asked by Paul
factor this polynomial function completely
f(x)=12x^4+10x^3-214x^2+198x+90
I found all the possible rational zeros but just cant seem to factor it all

If you found the rational zeros then it is easy to find the factors.
e.g. suppose one of the values is x = -2/3
then the corresponding facor is (3x+2)
so just use your zeros and set up the factors from those following the pattern from above.
