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 : a²x² + (ax² + 1) x + a

Factorise by the grouping method : a (a -4) - a + 4

factorise: x² + 5xy + 4y²

factorise: (2a + b)² + 5(2a + b) + 6

factorise: 1 − (2x + 3y) − 6(2x + 3y)²

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

Factorise the following by grouping the terms:
x(x - 4)- x + 4

Factorise the following by grouping the terms:

Factorise the following by grouping the terms:
x + y + m(x + y)

Factorise the following by grouping the terms:

`(1)/(25x^2) + 16x^2 + (8)/(5) - 12x - (3)/(5x)`
