Approximate the real number solution (s) to the polynomial function f (x) = x3 + 2x2 - 5x - 6.

The problem ask to find and calculate the approximate real number solution to the polynomial function of f (x) = x3+2x2-5x-6. So base on my calculation and further solution about the problem, i came up with an answer of x = - 1, - 3, 2. I hope you are satisfied with my answer and feel free to ask for more

The answer is 3,1,-2. If you factor it then the equation would be, f (x) = (x-3) (x-1) (x+2). Then set each term then you would get x-3=0, x-1=0, x+2=0. Then solve algebraically and you would get 3,1,-2
