Answer 2

Zeros of of the polynomial f (x ) = -3, -3 , 2/3

Step-by-step explanation:

f(x) = 3x³ + 16 x² + 15 x - 18

x = 2/3

x - 2/3 = 0

3x -2 = 0

If we divide  3x³ + 16 x² + 15 x - 18 by 3x -2

which is shown in picture so kindly check the picture ....

We get ,       x² + 6x +9 = 0

            x² + 3x + 3x + 9 = 0

           x (x +3) + 3( x+3) = 0

                     (x +3)(x+3) = 0

                                   x = -3, -3
