Methods of Solving Quadratic Equations

The quadratic equation is about the polynomial equation in the single variable where the highest exponent of a variable is only 2. If you want to know solving quadratic equations, you will have three main ways to solve the quadratic equation.

  1. Methods of Solving Quadratic Equations

  2. The first one is to factor the quadratic equation when you are able to do this, you can also use the quadratic formula or you can complete the square. If you want to use any of these methods, you have to be aware of the step by step to follow .

  3. Factoring of the quadratic equation • Combine the like terms and move them at just one side: you should start by factoring the equation by moving all the terms to go to one side of an equation and to keep the square root positive.

  4. In combining the term, then you should subtract or add the terms that are a square root, that have variable terms and these of constant. If the side does not have the remaining term, you may write 0 and the other side of the equal sign.

  5. Factoring of expression: if you want to factor expression, you will have to use the factors term and the factors of the constant term in order to multiply them and to add up the middle terms.

  6. You can then set every set in the parenthesis which equal to zero into the separate equation. This can lead in finding out the two values, and it can make an entire equation to be equal to zero. When you have finished factoring the equation, then you may put all the expression on every set of the parenthesis that equal to zero.

  7. When you have finished factoring the equation, then you may put all the expression on every set of the parenthesis that equal to zero. To get the multiplication of zero, there are rules, principles, and rules. This means that if any of the factors outside of the parentheses equal to zero, the one outside may also equal to zero.

  8. You can then solve each zeroed equation alone. In the quadratic equation, they can be two values for the x. You can find x for every possible value and one by one through isolating variables and writing down two variables for two solutions of the x like the final solution.

  9. The use of Quadratic Formula • You should start by combining the likes term and to move them from one side to another. You can move the terms from one side of an equal sign and to keep the square root term positive.

  10. When you are writing the terms, you should use the descending order for the degree and the term will come first and them the variable term and the rest is the constant term.

  11. After writing down the formula, you should identify the value of the quadratic equation and fill them into the formula.

  12. Calculate: after plugging in numbers, you can do remaining math in order to simply the negative and the positive sign, to multiply and to get the square of the remaining terms.

  13. You can then simplify the square root. When the number in the radical symbol is not that perfect, you can get the whole number. When the number does not have a perfect square, you will have to simplify it to reach to the simplest radical version.

  14. The third option is completing a square root • You can start by moving all the terms at one side of the equation and ensure that the square root is positive before putting the constant to its side and to continue with the procedure. • Check this out: https://quickmath.com
