12x^2 + 5x - 25 >_ 0
--------------
x=[-5+-sqrt(25-4*12*-25)]/24
x=[-5+-35]/24
x=[-40/24] or x=30/24
x=-5/3 or x=5/4
(3x+5)(4x-5)>=0
Draw a number line.
Plot the points x=-5/3 and x=5/4
Find the solution interval for the original problem
Graphing you would get:

Notice that the curve is above the x-axis for x<-5/3 and for x>5/4
