p(p^2 – 2(p)(3q) + (3q)^2) solve the ^2 part first

p(p^2 -6pq + 9q^2) simplify

p^3 – 6p^2q + 9pq^2 distribute the first “p”

I am assuming what you want is for this equation to be fully expanded as you didn’t say to sovle p or q.

(p^3-6qp^2+9pq^2)

i have no idea if that is right i did it logically way i was tought. if you have to sub the variables make sure you use the order of operations. what level math is this? sorry if that is wrong i think its right…capital P is same as small p right? just cuz it was in the beginning?

P(p^2-6pq+9q^2)

Pp^2-6Ppq+9Pq^2

but… if it is p(p-3q)^2 then,

p(p^2-6pq+9q^2)

p^3-6p^2q+9pq^2
