How many factors are in the expression $(4 x^{3}) (8 x + 90) (3 x^{2} + y)$ ?

1 pt DOK: 2

10.

To fine the roots of the equation $x^{3} - 8 x^{2} - 3 x + 90 = 0$ , all the possible rational roots were tested with the function $f (x) = x^{3} - 8 x - 3 x + 90$ . Is x=-3 a root of the equation?

No, because $f (- 3) \neq 0$ .

No, because $f (- 3) = 0$ .

Yes, because $f (- 3) \neq 0$ .

Yes, because $f (- 3) = 0$ .
