Factoring Quadratics
Equations such as x2 = 64, x2 -5x = 0, and x2 + 4x = 5 are called quadratic equations. This is because in each of these equations the greatest exponent of any variable is 2. Standard Form of Quadratic Equations: ax2 + bx + c = 0

SOLVING QUADRATIC EQUATIONS BY COMPLETING-THE-SQUARE. Using the square root method to solve a quadratic equation only works if we can write the quadratic equation so that one side is the square of a binomial. To write the square of a binomial, we start with a perfect square trinomial, i.e., a trinomial that can be factored into two identical ...

This activity can serve as an introduction to quadratic equations. Students will use a CBL held at the end of a large PVC pipe held at an incline, then roll a tennis ball up the pipe and use the CBL to measure the ball’s distance from the CBL. This can then be related to the equation relating a projectile’s height above ground to the time ...

Solving quadratic equations (equations with x2 can be done in different ways. We will use two different methods. What both methods have in common is that the equation has to be set to = 0. For instance, if the equation was x2 – 22 = 9x, you would have to subtract 9x from both sides of the equal sign so the equation would be x2 – 9x – 22 ...

Solution of Quadratic Equations by Completing the Square. You are now ready to solve equations by completing the square. In this method, the left-hand side of a quadratic equation is solved by completing the square so that it becomes a perfect square trinomial which can be written in the form (x + p)2 = d.
