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. Factoring The equation can be written in the equivalent form of The only way that a product can equal zero is if one or both of the factors equal zero. Completing the square Subtract 5 from both sides of the equation. Add to both sides of the equation. Factor the left side and simplify the right side.
