In this mini-lesson, you'll learn how to determine the roots of an equation by the graphical method and by the factorization method. To find the roots of a given quadratic equation by graphical method, we plug in some values in for x, calculate the values of y, and draw a graph through the ordered pairs of x and y. In case of the factorization method, we factor the quadratic equation to find the roots of the equation.

Solve quadratic equations by inspection (e.g., for x² = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b.
