MAFS.912.A-REI.2.4: Solve quadratic equations in one variable.
a. Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x – p)² = q that has the same solutions.
Derive the quadratic formula from this form.
b. 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.

About Media4Math
Our Mission
Media4Math's mission is to educate 21st-century students in real-world applications of math with digital technology. We bring math to life in your classroom with a rich blend of resources to inspire your students to learn. Our philosophy is that the procedural side of math is a prerequisite to using it, but we also find that real-world math applications can provide motivation and even inspiration for math students. Math is its own language and it has important stories to tell. While many of our resources are for procedural skills, there are many resources that are real-world applications of math. Some of these resources rely on partnerships with other educational publishers.
