please Solve this problem

Answer 1

This is not possible mate ..
I think your question is to prove
$(a + b) {}^{2} = a {}^{2} + b {}^{2} + 2ab$
so here is your answer
$(a + b) {}^{2} = (a + b)(a + b)$
$= a(a + b) + b(a + b)$
$= a {}^{2} + ab + ab + b {}^{2}$
$= a {}^{2} + 2ab + b {}^{2}$
$hence \: proved \:$
