Question

Write the coefficient of x2 in the expansion of (x +4)3​

Answer 1

$\huge \bigstar { \underline{ \mathtt{ \red{A}{ \pink{n}{ \color{blue}{s}{ \color{gold}{w}{ \color{aqua}{e}{ \color{lime}{r}}}}}}}}}★$

(x + 4)³

x³ + 3(x)²4 + 3x(4)² + 4²

x³ + 12x² + 48x + 16

.

So, The coefficient of x² is 12.
