Question

if P + Q equal to 12 and PQ equal to 22 then find p square + Q square ​

Answer 1

Answer:

p+q=12

q=12-p.....(1)

pq=22

q=22/p

12-p=22/p

12(p)-p(p)=22

12p-p(sq.)=22

p(p)-12p-22=0

.....................

solve this eq.

Step-by-step explanation:

Answer 2

Answer:

100

Step-by-step explanation:

We know p + q = 12 and we also know that pq = 22. Substituting these values in the right hand side of the equation we just got above. 12² - (2 x 22) = 144 - 44 = 100 which is your answer.
