The formula for computing the real roots of the above quadratic equations form remains the same. Thanks & Regards, Prashant S Akerkar Last edited by skipjack; March 27th, 2019 at 06:25 AM.

Tip: The usual notation for a square is ^2. For example, your quadratic would be ax^2 + bx + c. There are no restrictions on a, b, and c. They are usually taken to be integers for educational purposes, but they can be real numbers. (They can even be taken to be complex numbers if you like.)
