Quadratic Equation Worksheets Methods to Solve Quadratic Equations A quadratic equation is an equation that can be written as ax ² + bx + c where a ≠ 0. In other words, a quadratic equation must have a squared term as its highest power. Below are the 4 methods to solve quadratic ...
Solve each equation to get a solution to the binomial. For x^2 – 9 = 0, for example, x – 3 = 0 and x + 3 = 0. Solve each equation to get x = 3, -3. If one of the equations is a trinomial, such as x^2 + 2x + 4 = 0, solve it using the quadratic formula, which...
We will solve the general quadratic equation by the method of completing the square. This is to obtain an x2term with a coefficient of 1. This we did in the previous section many times. We must add to each side. This form is called thequadratic formulaand represents the solution to all...
