Answer:
The polynomial is x^2 - 225.
Step-by-step explanation:
We know that the quadratic polynomial is x2 - (sum of the zeros) b + product of the zeroes.
Here sum of the zeroes is 0. And the product of the zeroes is -225.
Therefore the answer.

Given :
Find the quadratic polynomial whose zeros are root 15 and minus root 15
To find :
Find the quadratic polynomial
Solution :
Let the polynomial be ax² + bx + c and its zeros ,
Then,
Sum of zeros
Product of zeros
a = 1 b = 0 c = -15
So the required quadratic polynomial
=> ax² + bx + c
=> x² + 0×b + (-15)
=> x² - 15
