this is just like the one you posted in the HW forum ... multiplying two fractions ...x+1 x^2-2x+1
----- * --------
x-x^2 x^2-1==This isn't clear...is that 1 fraction or 2?
yeah you're right so far ... except you forgot to put the x after the 4 .. it's 2x^2-4x+1=0 not 2x^2-4+1=0 ... try using the quadratic formula for that ...
I am stuck with the 4th one, is it correct so far: 2x^2-4+1=0
What do you mean find the "domain"?
