What is the meaning of special product in college algebra?
As an example, the product of (a + b) (a - b) is equal to a
squared - b squared."Special product" simply means that there are
special cases, when multiplying polynomials, that are worth
memorizing. For example, if you know the above, then you can easily
start factoring any expression that contains the difference of two
perfect squares - for example, x squared minus 1, a to the power 6
minus b to the power 4, or even - if you start using complex
numbers - a squared + b squared = a squared - (-1) b squared.
