Use the x-intercept method to find all real solutions of the equation.
x^3-7x^2+4x+12=0

a.

Step-by-step explanation:

The given equation is

To find all real solutions using the x-intercept method, we to graph the corresponding function using a graphing tool.

The corresponding function is;

The real solutions to , are the x-intercepts of the graph of the corresponding function.

From the graph the x-intercepts are

(-1,0),(2,0) and (6,0).

Therefore the real solutions are
