Answer 2

Answer:

ab = -5

Step-by-step explanation:

Given quadratic  polynomial  is -  2x² + 5x - 10

Comparing the given quadratic polynomial with the general quadratic polynomial Ax² + Bx + C , we have ;

A = 2

B = 5

C = -10

Also ,

It is given that , a and b are the zeros of the given quadratic polynomial .

Thus ,

=> Sum of zeros = -B/A

=> a + b = -5/2

Also ,

=> Product of zeros = C/A

=> a × b = -10/2

=> ab = -5

Hence ,

ab = -5
