Quadratic equations are very common in algebra. The graph of a quadratic equation has the shape of a parabola. Quadratic Equations Explained A quadratic equation is an equation that looks like this: ax 2 +bx+c = 0, where a, b, and c are numbers, called coefficients. Example: x 2 +3x+4 = 0 You can think about a quadratic equation in terms of a graph of a quadratic function, which is called a equation means that you have to find the points on the horizontal axis (x) where the graph.
