Answer 2

Given :-

• (x + 3) (x + 3)

Solution :-

$\implies \: (x \: + \: a)(x \: + \: b)$

$\implies \: x {}^{2} \: + (a \: + \: b) \: x \: + \: ab$

$\implies(x \: + \: 3)(x \: + \: 3)$

$\implies \: x {}^{2} \: + \: (3 \: + \: 3) \: x \: + \: 3 \: \times \: 3$

$\implies \: x {}^{2} \: + \: 6x \: + \: 9$
