Hi Stef, I assume that this is a fraction with 3x^{2}  27 in the numerator and x + 3 in the denominator. The numerator has a common factor of 3 so it can be factored as
But is a difference of squares so the numerator can be factored further to give
Now place the factored numerator over the denominator and simplify. Penny
