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.
