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. Derive the quadratic formula from this form. 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. Solve quadratic equations in one variable. For example, find the points of intersection between the line y = -3x and the circle x2 + y2 = 3. Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. By the end of this playlist, students will be able to understand and solve problems involving quadratic equations. The playlist is an excellent resource for students to review or study for a test or final.
