Factorise: A2 +5a - 6

factorise: a² +5a - 6

Sum

a² +5a - 6

= a2 + 6a - a - 6

= a (a + 6) - 1 (a + 6)

= (a + 6) (a - 1)

Factorise by the grouping method:

ab (x² + 1) + x (a² + b²)

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

Factorise by the grouping method : y² - (a + b) y + ab

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 : a² - ab - ca + bc

Factorise : - x²y - x + 3xy + 3

factorise: 2a² + 7a + 6
