Step-by-step explanation:
A quadratic equation is a equation with a degree of 2. Below are the 5 ways to solve a quadratic equation.
- Factoring - First, make sure that one side of the equation is 0. Turn the equation into a product of two binomials and set each one to 0. Solve both to get both solutions.
- Completing the Square - Add to both sides such that one side becomes a square of a binomial. Square root both sides and solve with algebra.
- Square Roots - If one side of the equation is a perfect square, square root both sides and solve normally.
- Graphing - Make one side of the equation 0 and graph. The x-intercepts are the solutions.
- Quadratic Formula - First, make the equation follow the form [tex]ax^2+bx+c=0[/tex]. Then, use the formula [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex] to get the solutions.
