Yes, those are the three main methods of solving a quadratic equation.
1. Completing the square: This method involves rearranging the equation to create a perfect square trinomial, which can then be easily solved.
2. Factorization: This method involves factoring the quadratic equation into two binomials and setting each binomial equal to zero.
3. Quadratic formula: This method involves using the quadratic formula, which is x = (-b ± √(b^2 - 4ac)) / (2a), where a, b, and c are the coefficients of the quadratic equation.
