Question

Factorise the following:
(i) 20 a3– 25a2b
(ii) 10p2qr + 12p2q2r -16p2qr3

Answer 1

Step-by-step explanation:

i. 20a^3 - 25a^2 b

Since both terms are divisible by 5a^2 therefore we shall take 5a^2 common so we get

5a^2(4a - 5b)

This is the answer for the first one

The second sum is not understandable
