Question

(a+b)2= A2+2ab+b2
But how tell with full explanation​

Answer 1

$\Large{\underline{\underline{\bold{✯Required\;To\;Prove:}}}}$

• $\sf{(a+b)² = a²+b²+2ab}$

$\Large{\underline{\underline{\blue{\bold{✄Proof:}}}}}$

${(a + b)}^{2} \\ (a + b)(a + b) \\ {a}^{2} + ab + ba + {b}^{2} \\ {a}^{2} + 2ab + {b}^{2}$

Hence, Proved

• $\red{\bold{(a+b)² = a²+b²+2ab}}$
