Answer 1

$<b>HELLO !$

Hi we can solve this by using (a+b)^2


NOW,

(9p)^2+(5q)^2+2×9p×5q


From above a=9p and b=5q

put this value in (a+b)^2

=(9p+5q)^2

=(9p+5q)(9p+5q)

Answer 2

$\huge{ \blue{ \boxed{ \boxed{Hi}}}}$
$= 81p {}^{2} + 90pq + 25q {}^{2}$
$= (9p) {}^{2} + (2 \times 9p \times 5q) + (5q) {}^{2}$
$= (9p + 5q) {}^{2}$
$= (9p + 5q)(9p + 5q)$
