Any other quadratic equation is best solved by using the Quadratic Formula. If the equation fits the form ax 2 = k or a( x − h) 2 = k, it can easily be solved by using the Square Root Property. If the quadratic factors easily, this method is very quick.

How to identify the most appropriate method to solve a quadratic equation.Quadratic Formula: x b±b2 4ac 2a x b ± b 2 4 a c 2 a. The quadratic formula is most efficient for solving these more difficult quadratic equations. For equations with real solutions, you can use the graphing tool to visualize the solutions. Some quadratic equations are not factorable and also would result in a mess of fractions if completing the square is used to solve them (example: 6x2 + 7x - 8 0). The Quadratic Formula Calculator finds solutions to quadratic equations with real coefficients. if b 2 − 4 ac if b 2 − 4 ac = 0, the equation has 1 real solution.If b 2 − 4 ac > 0, the equation has 2 real solutions.For a quadratic equation of the form ax 2 + bx + c = 0, Multiply both sides of the equation by the least common denominator for the fractions appearing in the equation.Using the Discriminant, b 2 − 4 ac, to Determine the Number and Type of Solutions of a Quadratic Equation Learn how to Solve Quadratic Equations Involving Fractions by using the Factoring Method.Then substitute in the values of a, b, c. Write the quadratic equation in standard form, ax 2 + bx + c = 0.How to solve a quadratic equation using the Quadratic Formula. Equations With Fractions Grade 9Do you need more videos I have a complete online course with way more content.Click here.We start with the standard form of a quadratic equation and solve it for x by completing the square. Now we will go through the steps of completing the square using the general form of a quadratic equation to solve a quadratic equation for x. We have already seen how to solve a formula for a specific variable ‘in general’, so that we would do the algebraic steps only once, and then use the new formula to find the value of the specific variable. In this section we will derive and use a formula to find the solution of a quadratic equation. Mathematicians look for patterns when they do things over and over in order to make their work easier. By the end of the exercise set, you may have been wondering ‘isn’t there an easier way to do this?’ The answer is ‘yes’. When we solved quadratic equations in the last section by completing the square, we took the same steps every time. Solve Quadratic Equations Using the Quadratic Formula
