The sum of the zeros of the cubic polynomial 2x³ − 5x² + 3x − 1 is:

5/2. For ax³ + bx² + cx + d the sum of the zeros is −b/a. Here a = 2 and b = −5, so the sum is −(−5)/2 = 5/2.

The sum of the zeros of the cubic polynomial $2 x^{3} - 5 x^{2} + 3 x - 1$ is:

For

a x^{3} + b x^{2} + c x + d

the sum of the zeros is −

b

/a. Here

a = 2

and

b = - 5

, so the sum is

- (- 5) /2 = 5/2

Answer: C) 5/2
