Question

Factorisation of cubic polynomial 1example

Answer 1

Answer:

Group the polynomial into two sections. Grouping the polynomial into two sections will let you attack each section individually.[1]

Say we're working with the polynomial x3 + 3x2 - 6x - 18 = 0. Let's group it into (x3 + 3x2) and (- 6x - 18)
