Question

using sutible identity solve the following.a.(2x+3)(2x+3)​

Answer 1

___________________________________________

GIVEN :

$\bigstar$using suitable identity solve the following:

• (2x+3)(2x+3)

___________________________________________

USING IDENTITY :

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

___________________________________________

ANSWER :

☆ note -

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

☆ so,

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

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \longmapsto{ \boxed{\boxed{\boxed{\underline{\sf{= {2x}^{2} + 12x + 9}}}}}}$

FINAL SOLUTION :

$\huge\sf{ \implies{2x}^{2} + 12x + 9}$
