How to fill out solving quadratics by factoring

Point by Point Guide to Solving Quadratics by Factoring:

1. Identify the quadratic equation: Start by locating the quadratic equation that needs to be solved. It should be in the form of ax^2 + bx + c = 0, where a, b, and c are coefficients.
2. Check if the quadratic equation can be factored: Determine if the quadratic equation can be factored by looking for common factors or using factoring techniques such as the difference of squares, perfect square trinomials, or grouping.
3. Set the equation equal to zero: Rearrange the factored equation to set it equal to zero. This step is important since solving quadratic equations by factoring involves finding the x-values that make the equation equal to zero.
4. Apply the zero product property: The zero product property states that if ab = 0, then either a = 0 or b = 0. Apply this property to each factor of the equation and set them equal to zero.
5. Solve for x: Solve each equation obtained from applying the zero product property to find the possible values of x that satisfy the quadratic equation.
6. Check the solutions: Substitute the values of x obtained from step 5 back into the original equation to verify if they indeed solve the quadratic equation.
7. Write the solutions: Write the solutions in the form of (x = value1) and (x = value2), if there are two solutions, or (x = value) if there is only one solution.
