If α and β are the zeros of the polynomial f(x) = x2 + x – 2, find the value of
It is given in the question that,
Zeros of the polynomial x2 + x - 2 are
Now by using the relationship between the zeros of the quadratic polynomial we have:
Sum of zeros = and product of zeros =
= - 1 and
Now, we have:
