Question

factorise a² – 2ab + b² – c²​

Answer 1

Answer:

(a-b+c) (a-b-c)

Step-by-step explanation:

given expression

a^2-2ab+b^2-c^2

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

(a-b)^2 - c^2

factorization

a^2-2ab+b^2-c^2

(a-b+c) (a-b-c)

Answer 2

(a²-2ab+b²)-c² = (a-b)²-c² =  Take the formula a²-b² where a=a-b and b=c .

Then (a-b)²-c² =[(a - b) + c][(a - b) - c] .
