Question

Simplify p² - q²/pq - pq-q²/pq - p2​

Answer 1

Step-by-step explanation:

Given, p+q=12 and pq=22

We know that, (p+q)  

2

=p  

2

+q  

2

+2pq   ... (i)

By putting the given values in equation (i),

(12)  

2

=p  

2

+q  

2

+2(22)

144=p  

2

+q  

2

+44

144—44=p  

2

+q  

2

 

100=p  

2

+q  

2

 

So. the value of p  

2

+q  

22

 is 100.
