We know that,

${ \longrightarrow \bf \qquad \: {(a + b)}^(2) = {a}^(2) + 2.a.b + {b}^(2) }$

Solution :

${ \longrightarrow \sf \qquad \: {4x}^(2) + 12x + 9 }$

We can also write it as,

${ \longrightarrow \sf \qquad \: {4x}^(2) + 12x + {3}^(2) }$

Now, using the formula, we'll solve the expression.

${ \longrightarrow \sf \qquad \: {2x}^(2) + 2.2x.3 + {3}^(2) }$

${ \longrightarrow \sf \qquad \: (2x + 3)^(2) }$

Since,

Therefore,
