Answer variants:

$p^{2} + 2 pq + q^{2}$

$(x - 2) and (x + 2)$

$p^{2} + 2 pq - q^{2}$

$x^{2} + 25$

$2 \times 2 \times 2 \times 3 \times a \times b \times b \times c \times c$

$x^{2} - 25$

$2 \times 2 \times 2 \times 3 \times a \times b \times c$

$(x - 2) and (x - 2)$

$(x + 2) and (x + 2)$

$p^{2} - 2 pq + q^{2}$
