For any quadratic equation of the form ax² + bx + c = 0, the solutions are:
The expression under the square root, b² - 4ac, is called the discriminant. It tells us:
This theorem connects differentiation and integration — the two main operations of calculus:
Where F is any antiderivative of f, meaning F'(x) = f(x). This tells us that:
