Question

1. (i) 12x +15 (ii) 14m-21 (iii) 9n -12n 3 13,2​

Answer 1

Answer:

12x + 15

Taking 3 as common from the whole, we get,

12x + 15 = 3(4x + 5).

(ii) 14m – 21,

Taking 7 as common from the whole, we get,

14m – 21 = 7(2m – 3)

(iii) 9n – 12n2,

Taking 3n as common from the whole, we get,

9n – 12n2 = 3n (3 – 4n).
