Question

If a and b are the zeroes of the quadratic polynomial f(x)= x2-1 find a quadratic polynomial whose zeros are 2a/b and 2b/a

Answer 1

from the above polynomial it is clear that the values of a and b 1 or -1
Hence the zeros of next polynomial must be 2 or -2
then the given polynomial is
f(x) = x^2 - 4
