Completing the square and using the quadratic formula are two ways to solve quadratic equations. Each method has its own challenges.

1. Completing the Square:

   • With this method, you change the equation into the form $y = a(x - h)^2 + k$. This can be tricky.
   • You have to find a specific number to complete the square, which can be confusing, especially when the numbers are negative or if you have fractions.
   • Many students find it hard to change the equation without making mistakes.

2. Quadratic Formula:

   • The quadratic formula is $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$. It gives a clearer answer.
   • But figuring out $b^2 - 4ac$ can be tough. It’s important to know if there are real solutions or not.

In summary, while both methods can help you solve quadratic equations, they can be challenging for students in Grade 10.
