A quadratic equation is drawn as a curve on a set of axes. This type of curve is called a parabola and it is symmetrical. To draw the graph we need coordinates. We generate these coordinates by ...

Plot of a quadratic equation showing the classic parabola, made with NumPy and Matplotlib. Linear equation 3x + 5 plotted with SymPy. Plot of a Quadratic Equation created in SymPy.

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.

The option to input an equation is at the top-right corner of the calculator window. As you can see from the picture above, you can compute both linear and quadratic equations in the calculator.

Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have ...
