Factorise: 5 + 7x - 6x2

factorise: 5 + 7x - 6x²

Sum

5 + 7x - 6x²

= 5 + 10x - 3x - 6x²

= 5(1 + 2x) - 3x(1 + 2x)

= (1 + 2x)(5 - 3x)

Factorise by the grouping method: 16 (a + b)² - 4a - 4b

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise using the grouping method :
x (6x - 5y) - 4 (6x - 5y)²

Factorise : a³ -a² +a -1

Factorise : ax + 2bx + 3cx - 3a - 6b - 9c

factorise: 6 + 7b - 3b²

Factorise: 2(x + 2y)² − 5(x + 2y) + 2

factorise: a² - 23a -108

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

Factorise the following by grouping the terms:

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