    In order to solve the function 9x2 + 31x + 12 ≤ 0 you need to use the quadratic formula:
    x = [ -b ± sqrt(b^2 - 4ac) ] / 2a.
    a, b, and c are determined according to ax2 + bx + c : a = 9, b = 31, and c = 12.
    Because axhas apositive sign before it, the function look like this: 


    "", and not like this:
    "", and according to the x values found with the quadratic equations, you can draw a graph of the funcion, and from the graph you can determine what x values give y values that are bigger than 0, smaller than 0, or equal to 0.
