The ''U'' shaped graph of a quadratic is called a parabola. A quadratic equation has two solutions. Either two distinct real solutions, one double real solution or two imaginary solutions.
All methods start with setting the equation equal to zero.
Solve for x in the following equation. Simplify the equation. Therefore, we will not use this method. Completing the square Add 8 to both sides of the equation . Divide both sides of the equation by and simplify.
