Solve:
You can always solve a quadratic equation by:
a) The quadratic formula or
b) Completing the square.
Let's use the "completing-the-square" method.
Add 25 to both sides.
Now complete the square in x by adding the square of half the x-coefficient () to both sides of the equation.
Factor the left side and simplify the right side.
Now take the square root of both sides.
Finally, subtract 3 from both sides.
