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 - 2b + a² - 2a

Factorise by the grouping method:

ab (x² + 1) + x (a² + b²)

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise : 6a² - 3a²b - bc² + 2c²

Factorise : (a² − b²) c + (b² − c²)a

factorise: 6 + 7b - 3b²

factorise: x²y² - 3xy - 40

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

Factorise the following by grouping the terms:
4abx² + 49aby² + 14xy(a² + b²)

Factorise the following by grouping the terms:
xy(a² + 1) + a(x² + y²)
