Answer:

d.
x=-1,2,\:or\:5

Explanation:

The given equation is;


x^3-6x^2+3x+10=0

To solve by the x-intercept method we need to graph the corresponding function using a graphing calculator.

The corresponding function is


f(x)=x^3-6x^2+3x+10

The solution to
x^3-6x^2+3x+10=0 is where the graph touches the x-axis.

We can see from the graph that; the x-intercepts are;

(-1,0),(2,0) and (5,0).

Therefore the real solutions are:


x=-1,2,\:or\:5
