Factorise: X(3x + 14) + 8

factorise: x(3x + 14) + 8

Sum

x(3x + 14) + 8

= 3x² + 14x + 8

= 3x² + 12x +2x +8

= 3x(x + 4) + 2(x + 4)

= (x + 4)(3x + 2)

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

Factorise by the grouping method : a⁴ - 2a³ - 4a + 8

Factorise using the grouping method :
m (x - 3y)² + n (3y - x) + 5x - 15y

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

Factorise : a³ -a² +a -1

Factorise : x² - (a - 3)x - 3a

Factorise : x² - (b - 2)x - 2b

factorise: a² - 23a + 42

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

Factorise the following by grouping the terms:

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