explain how to graph a quadratic equation to someone who does not
know how. make sure you explain how to find the vertex-
formula to use. you should also teach them how to tell whether the
graph opens up or down and how to find the maximum or minimum
and zeros/solutions.

The term quadratic comes from the word quadrate meaning square or rectangular. Similarly, one of the definitions of the term quadratic is a square. In an algebraic sense, the definition of something quadratic involves the square and no higher power of an unknown quantity; second degree. So, for our purposes, we will be working with quadratic equations which mean that the highest degree we'll be encountering is a square. Normally, we see the standard quadratic equation written as the sum of three terms set equal to zero. Simply, the three terms include one that has an , one has an x, and one term is "by itself" with no or x.
