Find  the following  of  zero of the polynomial x3 + 3x2-3x-1

Let the given polynomial be .

The zeroes of the polynomial f(x) can be obtained by putting f(x) = 0.

Thus, the zeroes of the given polynomial are .

  • -3

zero of the polynomial x3+3x2-3x-1 is 1.

it can be hecked ny putting the value 1 at the place of x.

x3 + 3x2 - 3x - 1.

(1)3 + (3) (1)2 - 3(1) -1

1 + 3 - 3 - 1 = 0.

therfore, the zero of polynomial is 1.

  • 3

by trial method, the zero of the polynomial x3+3x2-3x-1 is 1.

it can be checked by putting the value 1 at the place of x.

x3 + 3x2 - 3x - 1.

(1)3 + (3) (1)2 - 3(1) -1

1 + 3 - 3 - 1 = 0.

therfore, the zero of polynomial is 1.
