While this question may appear unfamiliar at first, it is just a quadratic equation in disguise. Rearranging such that it equals 0:

x^2 + 5x - 36 = 0

Now this equation is re...

At first this looks quite daunting as it combines a number of different indices (powers) and a fraction. 

The rules for indices are just something that you have to learn - so don't worry ...

It is first important to get the equation to equal 0, so to do this you minus 12 from each side of the equals symbol, giving youX^2 +13X+36=0Now it is time to think about factorising!The best trick for th...
