i will mark you as brainliest who will answer first

Answer 1

(a+b+c)2 =(a×x)=a2+2ax+x2

Answer 2

Answer:

I don't know whether I am right or not, but still I will try

Step-by-step explanation:

let us consider that 2×a×b=C^2,

then as seen in the given formula a^2+b^2+c^2-(1)

putting c^2 in -(1),we get

a^2+b^2+2ab

we know the identity a^2+b^2+2ab=(a+b)^2

thus we get the formula as (a+b)^2.
