Yes, there is another formula that can be used to find the roots of a quadratic equation, known as completing the square. This method involves manipulating the equation to create a perfect square trinomial, which can then be easily factored to find the roots.

Complete the Square
This method involves completing the square of the quadratic expression to factor it:
- Step 1: Move the constant term to the other side of the equation. - Step 2: Divide both sides of the equation by the coefficient of x². This makes the coefficient of x² equal to 1. - Step 3: Add and subtract the square of half the coefficient of x. - Step 4: Factor the left-hand side as a perfect square trinomial. - Step 5: Take the square root of both sides (remembering to include both the positive and negative roots). - Step 6: Solve for x by isolating it on one side of the equation.
Example:
Factor the quadratic equation: x² + 6x + 8 = 0
Solution:
- Move the constant 8 to the other side: x² + 6x = -8 - Divide both sides by 1: x² + 6x = -8 - Add and subtract (6/2)² = 9: x² + 6x + 9 = 1 - Factor the left-hand side: (x + 3)² = 1 - Take the square root of both sides: x + 3 = ±1 - Solve for x: x = -3 ± 1
Therefore, the factors of the quadratic equation are (x + 2) and (x + 4).
