1.	y2 + 2y – 3=? A. (y - 1) (y + 3) B. (y + 1) (y - 3) C. (y - 1) (y - 3) D. (y + 2) (y - 3)
Answer» y² + 2y – 3 Factorizing the equation and taking y and – 1 as common, = y² + 3y – y – 3 = y(y + 3) – 1(y + 3) = (y + 3)(y – 1).

y2 + 2y – 3=? A. (y - 1) (y + 3) B. (y + 1) (y - 3) C. (y - 1) (y - 3) D. (y + 2) (y - 3)

Answer»

y² + 2y – 3

Factorizing the equation and taking y and – 1 as common,

= y² + 3y – y – 3

= y(y + 3) – 1(y + 3)

= (y + 3)(y – 1).
