Question

if 2(a square +b square)=(a+b)whole race to square prove that a=b

Answer 1

(a+b)^2=a^2 +b^2 +2ab

yu sae 2*(a^2+b^2)=a^2 +b^2 +2ab

2a^2 +2b^2=a^2 +b^2+2ab

subtrakt (a^2 + b^2) from both sides & yu get

a^2 +b^2=2ab

reesumabel tu thank oenlee wae that kan be true is if a=b

as tu pruev it, dont no
