If you've dealt with linear examples, then make this one linear as well....
(x^2-9) can be factored into two linear polynomials. You should be able to solve it from there.
After looking at some questions i've been set to look at I have done them all but one. Can anybody take me through the method with my example ? I have done some with linear dinominators but now I have squares in the fraction.
4x2 - 2(x2 -9)(x-2)
Help would be grately appreciated.
