Answer 2

${\large{\underline{\textbf{\red{Answer :-}}}}}$

We have to find

♣ (x + 3)²

Concept :- Here, we see the question it tell us (x+3)² means it like that (a+b)² , if we use the formula of (a+b)² then we will get the accurate answer of this.

Formula :- (a + b)² = a² + 2ab + b²

According to the formula

$\small\sf\longmapsto{(x + 3) {}^{2} = x {}^{2} + 2(x)(3) + (3) {}^{2} } \\ \\ \small\sf\longmapsto{(x + 3) {}^{2} = x {}^{2} + 6x + 9} \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Final answer : x² + 6x + 9
