Question

factorize (a+b+c)^{2}+2(a+b)(a-b-c)+(a-b-c)​

Answer 1

(a+b+c)^2can you know this formula so you to learn all algebra formula than you can easlly solve this

Answer 2

$\huge\bf\red{aNsWEr}$

let a+b+c=x

a-b-c = y

solution:-

$x^{2}+2xy+y^{2} \\ (x+y)^{2} \\ [a+b+c+a-b-c]^{2} \\ (2a)^{2} \\ 4a^{2}$

Thanks
