Question 4001: The lesson is on "Solving Quadratic Equations by Using the Quadratic Formula. How do you solve by graphing on problems like x to the 2nd -2x-24=0 or how do u graph problems with irrational roots?

You can put this solution on YOUR website!
by graphing i take it you mean actually plotting the curve?

If so, irrational roots are not a problem - > plot the graph as normal and you will find the curve does not cross the x-axis hence no real solution: this is all a (x,y) Cartesian graph can tell you.
