Q11 of 113 Page 50

Find the zeros of the following quadratic polynomials and verify the relationship between the zeros and the coefficients:

5y2 + 10y

Let f(x) = 5y2 + 10y

Put f(x) = 0


5y2 + 10y = 0


(5y) (y + 2) = 0


∴ x =0 or x = -2


Now, sum of zeroes


Product of zeroes


Hence, relationship verified.
