Solving Quadratic Equations Worksheets

Quadratic Equation-How to Solve Quadratic Equation? An equation of the second degree is known as the Quadratic equation, which means it contains at least one term that is squared. The standard form is, ax² + bx + c = 0. With a, b, and c being constants, or numerical coefficients. x is an unknown variable. The graph of a quadratic function is a curve called a parabola. Since the quadratic equation includes only one unknown, it's called univariate. The quadratic equation only has powers of x that are non-negative numbers, and so it is a polynomial equation. To be specific, it is a second-degree polynomial equation, because the greatest power is two. ax² + bx + c = 0 There are three basic methods for solving quadratic equations: factoring, using the quadratic formula, and completing the square. But let's talk about solving a quadratic equation by factoring, 1. Put all terms on one side of the equal sign, leaving zero on the other side. 2. Factor. 3. Set each factor equal to zero. 4. Solve each of these equations. 5. Check by inserting your answer in the original equation.
