Given the following equation:
[tex]x^3-4x^2-20x=-48[/tex]
We will find the real solutions to the equation by graphing.
We will rewrite the given equation as follows:
[tex]x^3-4x^2-20x+48=0[/tex]
The graph of the function will be as shown in the following figure:
As shown the function has 3 real solutions which are the x-intercepts
So, the answer will be:
[tex]x=-4,2,6[/tex]
