Factorise: 4 + Y - 14y2

factorise: 4 + y - 14y²

Sum

4 + y - 14y²

= 4 + 8y - 7y - 14y²

= 4 (1 + 2y) - 7y (1 + 2y)

= (1 + 2y)(4 - 7y)

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

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`

Factorize using the grouping method:

x² + y² + x + y + 2xy

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

Factorise : a³ - a² - ab + a + b - 1

Factorise : 2ab²c - 2a + 3b³c - 3b - 4b²c² + 4c

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

Factorise the following by grouping the terms:
15xy - 9x - 25y + 15

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