Factorise : X2 - (B - 2)X - 2b

Factorise : x² - (b - 2)x - 2b

बेरीज

x² - (b - 2)x - 2b

= x² - bx + 2x - 2b

= x (x - b) + 2(x - b)

= (x - b) (x + 2)

m (x - 3y)² + n (3y - x) + 5x - 15y

Factorise : a³ -a² +a -1

Factorise : xy - ay - ax + a² + bx - ab

factorise: x² + 4x + 3

factorise: (2a + b)² + 5(2a + b) + 6

factorise: 1 − (2x + 3y) − 6(2x + 3y)²

factorise: 5x² - 4xy - 12y²
