Common terms are the negative sign, one power of p, four powers of q and three powers of r.
-p^2 q^4 r^5 - p q^5 r^3
= take out common terms here (leave behind the remaining terms + leave behind the remaining terms)
= -p q^4 r^3 (p r^2 PLUS q^1)
= -p q^4 r^3 (p r^2 + q)
PLUS is because we have already taken out the common negative sign earlier.
-p^2 q^4 r^5 - p q^5 r^3
= take out common terms here (leave behind the remaining terms + leave behind the remaining terms)
= -p q^4 r^3 (p r^2 PLUS q^1)
= -p q^4 r^3 (p r^2 + q)
PLUS is because we have already taken out the common negative sign earlier.
