What are the different methods for solving a quadratic equation.

The answer to your question is all of them

Step-by-step explanation:

I think all the methods listed here can help to solve quadratic equations.

Type of method                        Example

By factoring                      x² + 5x - 6 = 0                 (x + 6)(x - 5) = 0

By graphing                      see the graph below

Square roots                    x² - 18 = 0                        x = ±√18

Completing the square   x² + 12x + 32 = 0            x² + 12x + (6)²= -32 + (6)²

Quadratic formula              

the answer is c
