Answer:

Given quadratic polynomial is 2s2−(1+22)s+2

=2s2−s−22s+2

=s(2s−1)−2(2s−1)

=(2s−1)(s−2)

s=21 and s=2

The relationship between the zeroes and their coefficient,

Sum of the zeroes=−coefficient of s2coefficient of s

                              =−(2−(1+22))

                              =21+22

Also sum of the zeroes=21+2

                                        =21+22
