Question

factorise : a2 (b – c) + b (c – b) don't give me irrelevent answers​

Answer 1

Step-by-step explanation:

a²(b-c)+b(c-b)=0

multiplying both sides by -1 we get

-1[a²(b-c)+b(c-b)]=0

a²(c-b)-b(c-b)=0

(a²-b)(c-b)=0

a²-b=0 , c-b=0

a=√b , c=b

Answer 2

Answer:

a2(b-c) -b(b-c)

(b-c)(a2-b)
