You’re actually a life saver. You have taught me things better than my teacher has done. Without these videos that you have made I feel I would have gotten a bad grade in maths. Thanks!

Thanks just got this topic always thought you had to rationalise the denominator with the sa, e sign as it was but it’s actually the opposite in all cases.
