Factories:

i. x(x + 3) + 5(x + 3)


ii. 5x(x – 4) -7(x – 4)


iii. 2m(1 – n) +3(1 – n)

(i) x(x + 3) + 5(x + 3)


Taking x + 3 as common from the whole, we get,


(x + 3)(x + 5).


(ii) 5x(x – 4) -7(x – 4)


Taking x – 4 as common from the whole, we get,


= (x – 4)(5x – 7).


(iii) 2m(1 – n) +3(1 – n)


Taking 1 – n as common from the whole, we get,


(1 – n)(2m + 3).
