ALGEBRA SKILLS NEEDED
- Factoring - You need to be able to factor expressions and equations like it was second nature to you. Many of the problems in calculus will involve finding the roots of a function and for the most part that means factoring. Don't just concentrate on polynomial factoring, either; you need to be able to factor expressions with rational exponents. Here is an example of factoring out the greatest common factor, which is involves taking the smallest exponent on all of the common terms.Know how to recognize and factor the special patterns of the difference of two squares, the difference of two cubes, and the sum of two cubes. Know that the sum of two squares usually doesn't factor in the real world.
- Completing the Square - Another task that you will be called on to perform occasionally is completing the square. You need to be able to do this with both an equation and an expression. Examples of both are shown below.
- Simplifying Expressions - Much of your time in this course will be spent simplifying the results of an expression that you obtained. Know how to combine similar or like terms and know the properties of exponents like adding exponents when multiplying factors that have the same base or multiplying exponents when raising to a power.
