Question

Show the problem of p²+pr-q²+5pr?solve?

Answer 1

Answer:

Hey guys

Step-by-step explanation:

As per question

             p+q+r=0

⇒          p+q= -r

⇒         (p+q)³= (-r)³

⇒          p³+q³+3p²q+3pq²= -r³

⇒          p³+q³+r³ = -3pq(p+q)

⇒          p³+q³+r³=3pqr

⇒         (p³+q³+r³)/pqr=3

⇒          p²/qr+q²/pr+r²/pq = 3
