This video is an quick overview of an online editor for Java (and many other languages).
We can use this for all of our programming.Factoring quadratic expressions
This video shows you how to factor quadratic expressions in the form of
ax^2 + bx + c. where a, b, and c are integers.
In this video the quadratic expressions all have a = 1.
Being able to factor quadratic expressions will enable you to be able to solve quadratic equations; to be able to simplify rational algebraic expressions; to be able to find the zeros of a quadratic function.Finding the Product and Sum - Video
This video guides you throught the process of finding the two numbers that multiply (giving a product) and add (giving a sum) to the numbers in a quadratic expression. This is necessary to be able to factor quadratic eqpressions.
