# Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients:2x2 – 7x

Let f(x) = 2 x2 – 7x

In this the constant term is zero.

f(x) = 2 x2 – 7x

= x(2x – 7)

On putting f(x) = 0 , we get

x(2x – 7) = 0

2x – 7 = 0 or x = 0 or x = 0

Thus, the zeroes of the given polynomial 2x2 – 7x are 0 and Verification

Sum of zeroes or Product of zeroes or So, the relationship between the zeroes and the coefficients is verified.
