You can put this solution on YOUR website! I have no idea how to do this.
f(x)=xroot2-6x+4, g(x)=-x-1
I need to find f+g, f-g, f.g and f/g
----------
f+g = xsqrt(2)-6x+4 + -x-1 = (sqrt(2)-7)x+3
----------
f-g = xsqrt(2)-6x+4 -(-x-1)
f-g = (sqrt(2)-5)x + 5
-----------------------------
To get f*g multiply f and g
To get f/g divide
=======================
