Factorise : A2 + Ax + Ab + Bx

Factorise : a² + ax + ab + bx

Sum

a² + ax + ab + bx

= (a² + ax) + (ab + bx)

= a(a + x) + b (a + x)

= (a + x) (a + b)

Factorise by the grouping method:

ab (x² + 1) + x (a² + b²)

Factorise : a³ -a² +a -1

Factorise : 6a² - 3a²b - bc² + 2c²

Factorise : a(b − c) − d(c − b)

factorise: a² − 3a − 40

factorise: b(c - d)² + a(d - c) + 3(c - d)

Factorise the following by grouping the terms:
3ax² - 5bx² + 9az² + 6ay² - 10by² - 15bz²

Factorise the following by grouping the terms:
p²x² + (px² + 1)x + p

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

Factorise the following by grouping the terms:

`"p"^2 + (1)/"p"^2 - 2 - 5"p" + (5)/"p"`
