Question

simplyfy (a+b+c)^2-(a-b-c)^2​

Answer 1

Answer:

This can be done using x^2 - y^2 = (x+y)(x-y)

so, taking (a+b+c) as x and (a-b-c) as y

this will be

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

(a+b+c+a-b-c) × (a+b+c - a + b + c)

(2a) × (2bc)

= 4abc

Therefore, the answer is 4abc.

Hope it helps!!!!!
