Question

Factorize a3+ab(1-2a)-2b2

Answer 1

1-2a -2b -3(a+b)² = 1-2(a+b)-3(a+b)² =1- 3(a+ b) +(a+b) -3(a+b)² =1[1-3(a+b)]+(a+b)[1-3(a+b )] =[1-3(a+b)][1+(a+b)] =(1-3a-3b)(1+a+b).

Answer 2

Step-by-step explanation:

a^3 + ab (1 - 2a) - 2b^2

a^3 + ab - 2a^b - 2b^2

a(a^2+b) - 2b(a^2 + b)

(a^2+b) (a-2b)
