Question

If p2-3p+1=0 and find p2+1/p2​ & p3+1/p3

Answer 1

Answer:² - 3p + 1 = 0

_____________ [GIVEN]

• We have to find the value of p² +  

______________________________

Solution:

p² - 3p + 1 = 0

p² + 1 = 3p

Divide by p on both sides

 +  =  

p +  = 3

Now.. squaring on both sides..

 = (3)²

• (a + b)² = a² + b² + 2ab

 = 9

p² + 1/p^2 + 2 = 9

p² + 1/p^2  = 7
