1.	Factorise : ax + ay + bx + by A) (x + a) (y + b) B) (x + y) (a + b) C) (x + b) (y + a) D) (xy + ab)
Answer» B) (x + y) (a + b) Correct option is (B) (x + y) (a + b) ax + ay + bx + by \(=a(x+y)+b(x+y)\) = (a + b) (x + y)

Factorise : ax + ay + bx + by A) (x + a) (y + b) B) (x + y) (a + b) C) (x + b) (y + a) D) (xy + ab)

Answer»

B) (x + y) (a + b)

Correct option is (B) (x + y) (a + b)

ax + ay + bx + by \(=a(x+y)+b(x+y)\)

= (a + b) (x + y)
