Heya !!!
Let alpha be a one zero of the given polynomial.
Other zero will be 1/Alpha
P(X) = 5Z² + 13Z - P
Here,
A = 5 , B = 13 and C = -P
Product of zeroes = C/A
Alpha × 1/Alpha = -P/5
1 = -P/5
P = -5

Answer:
Hey
Here is your answer,
5z^2 + 13z - p = 0
Let the zeroes be alpha and 1/ alpha
Product of zeroes = c/a
Alpha x 1/alpha = -p/5
-p/5 = 1
p = -5
