WebbRevise how to simplify algebra using skills of expanding brackets and factorising expressions with this BBC Bitesize GCSE Maths Edexcel guide. WebbExample 1: Divide the complex numbers below. The first step is to write the original problem in fractional form. Since our denominator is 1 + 2i 1 + 2i, its conjugate is equal to 1 - 2i 1 − 2i. Remember to change only the sign of the imaginary term to get the conjugate.
