Question

Show that: (3/7 p - 7/6 q)² + pq = 9/49 p² + 49/36 q²​

Answer 1

Answer:p^2 + q^2 = 36

pq = 7

Now , (p+q)^2 = p^2 + q^2 + 2pq

= 36 + 2(7)

= 50

So, the answer is 50

Step-by-step explanation:

Answer 2

Answer:

(3/7p)2 = 9/49 p² + 49/36 q² - pq + pq

= 9/49 p² + 49/36 q²

So therefore 9/49 p² + 49/36 q² = 9/49 p² + 49/36 q²
