Question

If p+q=10 and pq=5,then the numerical value of p/q+q/p will be​

Answer 1

Answer:

18

Step-by-step explanation:

pq+qp=p2+q2pq

=(p+q)2−2pqpq=(10)2−2×55

=100−105=905=18

Answer 2

Answer:

18

Step-by-step explanation:

ANSWER

GIVEN : P+Q=10

P*Q=5

TO FIND : P/Q+Q/P

SOLUTION : TAKE LCM OF P/Q AND Q/P

=P^2+Q^2/PQ

=(P+Q)^2 - 2PQ

NOW, PUT VALUES GIVEN

=(10)^2 - 2(5) / 5

= 100 - 10 / 5

= 18
