Question

Using Identity find

(2x+3)^2​

Answer 1

$\huge\sf\blue{{\underline{answer}}:}$

$\bf{To~find:}$

$\bf{(2x+3)^{2}~using~suitable~identities}$

$\bf{Identity~to~be~used:}$

$\sf{~~~~~~~~~~(a+b)^{2}=a^{2}+2ab+b^{2}}$

$\sf\implies{(2x)^{2}+2(2x)(3)+(3)^{2}}$

$\sf\implies{4x^{2}+2(6x)+9}$

$\sf\implies{{\blue{\underline{\boxed{\bf 4x^{2}+12x+9}}}}}$
