Factorise: X2 + 4x + 3

factorise: x² + 4x + 3

योग

x² + 4x + 3

= x² + 3x + x + 3

= x(x + 3) + 1 (x + 3)

= (x + 3) (x + 1)

Factorise by the grouping method : a³ + a - 3a² - 3

Factorise by the grouping method : ab - 2b + a² - 2a

Factorize using the grouping method:

x² + y² + x + y + 2xy

Factorise : ab² - (a - c) b - c

factorise: a² − 3a − 40

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