If the \(n\)th term of a quadratic sequence is known, we can work out the terms in that sequence and also use knowledge of solving equations to determine if a specified number is a term in the ...

Number sequences are sets of numbers that follow a pattern or a rule. Each number in a sequence is called a term. There are some special sequences that you should recognise. The most important of ...

I recently needed to check some homework answers related to use of the quadratic formula. After realizing that it was getting tedious to do these by hand, I thought of using my calculator to solve ...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas. His ...
