... Complex Numbers With the addition of the imaginary unit, a new set of numbers was formed – the complex numbers. Definition of a Complex Number If a and b are real numbers, the number a + bi is a complex number, and it is said to be written in standard form. If b = 0, the number a + bi = a is a real ...

... We are looking for −5x so we take the values from Rows 1 and 2 in the first column, namely +1 and −3. We obtain the factorisation by reading along the appropriate row: 2x2 − 5x − 3 = (2x + 1)(x − 3). Notice that the table gives the factorisation of similar looking polynomials, e.g. 2x2 + x − 3 = (2x ...
