# Apply the quadratic formula

For questions 1-2, apply the quadratic formula to find the roots of the given function, and then graph the function.

For questions 3-4, factor the quadratic expression completely, and find the roots of the expression.

For question 5, complete the square, and find the roots of the quadratic equation.

In questions 6-10, use the discriminant to determine the number of solutions of the quadratic equation, and whether the solutions are real or complex. Note: It is not necessary to find the roots; just determine the number and types of solutions.
