Use the x-intercept method to find all real solutions of the equation.
x^2-9x^2+23x+15=0

b.

Step-by-step explanation:

The given equation is;

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

The corresponding function is

The solution to is where the graph touches the x-axis.

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

(1,0),(3,0) and (5,0).

Therefore the real solutions are:

5104.38 inches
