Chapter 5 Factorisation
Exercise 5.1 | Q 2.05

Factorise by the grouping method:

ab (x² + 1) + x (a² + b²)

Factorise by the grouping method :
`a^2 + 1/a^2 - 2 - 3a + 3/a`

Factorise using the grouping method :
a² + 4b² - 3a + 6b - 4ab

factorise: a² - 23a -108

factorise: x²y² - 3xy - 40

factorise: (3x - 2y)² - 5(3x - 2y) - 24

factorise: ax² + b²y - ab² - x²y

Factorise the following by grouping the terms:
9 + 3xy + x²y + 3x

Factorise the following by grouping the terms:
9x³ + 6x²y² - 4y³ - 6xy

Factorise the following by grouping the terms:
x² - (p + q)x + pq
