Turbo C Quadratic Equation

Hi. Good Day.

Is there anybody who can help me with my project in turbo C....
The logic must be like this, THE USER WILL INPUT A QUADRATIC EQUATION AND IT WILL BE DETERMINED IF THE EQUATION IS FACTORABLE OR NOT.

THE OUTPUT MUST BE LIKE THIS:
IF FACTORABLE THEN
SOLVE THE EQUATION
PRINT THE ANSWER
ELSE THEN
PRINT "THE EQUATION IS NOT FACTORABLE"

Any help...thanx a lot.
