How to fill out solving quadratic equations by

1. To solve a quadratic equation, follow these steps:
2. Write down the equation in the form ax^2 + bx + c = 0, where a, b, and c are constants.
3. Determine the values of a, b, and c.
4. Use the quadratic formula to find the solutions of the equation: x = (-b ± √(b^2 - 4ac))/(2a).
5. Simplify the equation by calculating the values inside the square root, if possible.
6. Solve the equation using the values obtained in step 4 to find the two possible solutions for x.
7. Check your solutions by substituting them back into the original equation to ensure they satisfy the equation.
