Quadratic equations not only described the orbits along which the planets moved round the Sun, but also gave a way to observe them more closely.

The shape of the path of a fly ball is a parabola. Suppose Mark McGuire hits a long fly ball in the Big baseball game. How long before it is caught or hits the ground? When will it be at a height of 10 feet?

Make measurements to determine which of several bowls is closest to paraboloid in shape.

Find the exact equation for a new telescope mirror with a given light-gathering power and focal length.

In some cases recognizing some common patterns in the equation will help you to factorize the quadratic equation.

This lesson covers many ways to solve quadratics, such as taking square roots, completing the square, and using the Quadratic Formula. But we'll start with solving by factoring.

How to solve quadratic equations using various methods

This was on my mind as I took the leap and created my Facebook profile. The blogs I keep allow me to have a minimal profile; I had the option to fill in a few more details on the personal profile I keep on Facebook. These are decisions that every educator using these technologies has to make.

"Participants also referenced the appropriateness of the content teachers provide. Typical responses included: 'Don't put anything about politics,' 'I wouldn't give out too much personal information or stuff you think your students might make fun of you about,' and 'Be cautious what people put on your wall.

Teachers giving computerized tests were unaware that students were instant-messaging one another across the room.

the school district chose to start an educational campaign. High school drama students created public service announcements that aired during morning announcements emphasizing the dangers of sharing private information online and the permanency of this information for college admissions counselors and future employers. Classes were offered for staff, parents, and the community, educating them on how kids are using technology and how they can talk to them. They saw immediate results; student postings online were suddenly more appropriate, teachers proactively worked to prevent misuse of technology, and parents and adults from the community attended classes and began discussing technology use with their children.
