In order to express this as a single fraction, you need both of the above terms to have a common denominator. You should be able to see that denominators of both terms already have a common factor of x-3. Try multiplying the first fraction by 2x−12x−1 and the second by x+4x+4, thinking about why this is valid and why it helps.
so i got (x-14)/((x+4)(2x-1)) can that be simplified or is it in its simplest form
Since the numerator is linear whilst the denominator is a quadratic (importantly expressed in it's simplest form), this can only be simplified further if the numerator is some multiple of one of the two linear factors in the denominator. Is this the case?
