You can put this solution on YOUR website!
x^4-(6x^3)+(4x^2)+7x-9
can somebody help me with fully factored form??
------
I graphed it.
graph%28400%2C400%2C-10%2C10%2C-10%2C10%2Cx%5E4-6x%5E3%2B4x%5E2%2B7x-9%29
===================================================
There do not seem to be any rational zeros.
You would have a hard time factoring this.
It has 2 Real zeroes around x = -1.1769
and x = +4.98956 and 2 complex zeroes.
