Question

If p- q = 3 and
p^2+q^2=29. Find the value of pq​

Answer 1

Step-by-step explanation:

p-q=3

Squaring on both sides, we get

p2+q2-2pq=9

Since it is given that,

p2+q2=29

So on putting value,

29-2pq = 9

2pq = 20

pq = 10

Answer : pq = 10

Answer 2

Answer:

pq =10

Step-by-step explanation:

Squaring on both sides, we get

p2+q2-2pq=9

Since it is given that,

p2+q2=29

So on putting value,

29-2pq = 9

2pq = 20

pq = 10

Answer : pq = 10
