###### 1. Verify that the numbers given alongside of the cubic polynomials below are their zeroes. Also verify the relationship between the zeroes and the coefficients in each case:

(i)

(ii)

Ans. (i) Comparing the given polynomial with , we get

and

= = = 0

= = 0

= = = 0

and are the zeroes of

Now,

=

And

= =

And =

###### (ii) Comparing the given polynomial with , we get

and

= = 0

= = 0

and are the zeroes of

Now,

=

And =

= =

And =
