ax2 + bx + c or a(x - h)2 + k
When graphed, quadratic equations of the form ax2 + bx + c or a(x - h)2 + k give a smooth U-shaped or a reverse U-shaped curve called a parabola. Graphing a quadratic equation is a matter of finding its vertex, direction, and, often, its x and y intercepts.

0=ax2+bx+c
A quadratic equation is a polynomial equation in a single variable where the highest exponent of the variable is 2.There are three main ways to solve quadratic equations: 1) to factor the quadratic equation if you can do so, 2) to use the quadratic formula, or 3) to complete the square. If you want to know how to master these three methods, just follow these steps.

x=−b±√b2−4ac
2a
A quadratic equation is written as ax^2+bx+c in its standard form. The vertex can be found by using the formula -b/(2a). For example, let's suppose our problem is to find out vertex (x,y) of the quadratic equation x^2+2x-3 . 1) Assess your a, b and c values. In this example, a=1, b=2 and c=-3.

  • Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations and is a good tool to have in your math tool belt.
