Question

If pq=3 and p+q=6 then find the value of (p2+q2)

Answer 1

Answer:

your answer

Step-by-step explanation:

p-q=3

p-q=3Squaring on both sides, we get

p-q=3Squaring on both sides, we getp2+q2-2pq=9

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,p2+q2=29

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,p2+q2=29So on putting value,

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,p2+q2=29So on putting value,29-2pq = 9

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,p2+q2=29So on putting value,29-2pq = 92pq = 20

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,p2+q2=29So on putting value,29-2pq = 92pq = 20pq = 10

p-q=3Squaring on both sides, we getp2+q2-2pq=9Since it is given that,p2+q2=29So on putting value,29-2pq = 92pq = 20pq = 10Answer : pq = 10
