there's nothing to solve. You have just presented a function of x.
Now, if you want to find where f(x)=0, that's a problem you can solve. On the way, we'll discover how to factor the quadratic, which is another kind of problem.
F(x) = (x-3)(x+1)
so, F(x)=0 when
x-3 = 0
or
x+1 = 0
Those I think you can handle, eh?
