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).
