.Derive the statement as corollaries of other theorems from the text or of statement you have proved true in the exercise.
Prove that if one solution to a quadratic equation of the form x^2+bx+c=0 is rational (where b and c are rational), then the other solutions is also rational. (Use the fact that if the solutions of the equation are r & s, then x^2+bx+c=(x-r)(x-s).)
This is a proof regarding rational solutions to quadratic equations.
