C++ equation solver-grapher program HELP!!

Hi:
My name is Carol, I was assigned to do a program that solves first and second
degree equations and then graphs them. For example: (ax+b=cx+d).
ax2(exp)+bx+c=o. I have a couple of tutorials and I have studied them extensively
but they don't help, I'm on my own, my teacher is horrible.
So PLEASe if you happen to have source code for something among these lines
or if you have an strategy for this please help me, I BEG YOU. THanks.

Are you supposed to graph them on paper, screen, or what? Let me know and maybe I can guide you in the right direction.
