If a and b are zeros of the polynomial f(x) = 5x^2+4x-9 then evaluate the following :a^3-b^3.

Results will be out: 854/ 125 (Please note that the result is a decimal number)

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
