What is expansion of (m + 2)² ?

1️⃣ 2m² + 4m + 4

2️⃣ m² + 2m + 4

3️⃣ m² - 4m + 4

4️⃣ m² + 4m + 4

$\huge{ \mathfrak{ \fcolorbox{magenta}{black}{ \color{magenta}{♡ Answer}}}}$

To find :

Expansion of (m + 2)²

Formula used :

$= >{(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2}$

Solⁿ :

$= > (m + 2)^{2} = {m}^{2} +( 2 \times m \times 2) + 2^{2}$

$= {m}^{2} + 4m+ 4$

Correct answer:-

4️⃣${m}^{2} + 4m+ 4$ ☑️

Hope it helps...
