Question

p+q =√13, p-q=√13. find pq
plz explain simple way it's important​

Answer 1

Answer:

pq = 0

Step-by-step explanation:

Given:

• p + q = √13
• p - q = √13

To Find:

• pq = ?

Solution:

We know that,

(p + q)² = (p - q)² + 4pq

=> (√13)² = (√13)² + 4pq

=> 13 = 13 + 4pq

=> 4pq = 13 - 13

=> 4pq = 0

=> pq = 0/4

pq = 0

Answer 2

pq = 0

Step-by-step explanation:

p+q = √13

p-q = √13

2p = 2√13

p=√13.

substitute p = √13 in p+q =√13

√13+q = √13

q=0

Therefore, p*q = √13*0

p*q =0
