Question

9p² + 25q² + 36r - 30pq - 60qr + 36 rp

Answer 1

Answer:

(5q-3p-6r)²

Step-by-step explanation:

$9p^2+25q^2+36r^2-30pq-60qr+36rp\\=(-3p)^2+(5q)^2+(-6r)^2+2(-3p)(5q)+2(5q)(-6r)+2(-3p)(-6r)\\=(5q-3p-6r)^2$

Answer 2

Answer:

• (5q-3p-6r)²

Step-by-step explanation:

• 9p2+25q 2+36r2-30pq-60qr+36rp\

=(-3p)2+(5q)2+(-6r)2+2(-3p)(5q)+2(5q)(-6r)

+2(-3p)(-6r)\

=(5q-3p-6r)2\
