Without the ability to factor polynomials you will be unable to complete this course. Rational Expressions – In this section we will define rational expressions and discuss adding, subtracting, multiplying and dividing them. Complex Numbers – Here is a very quick primer on complex numbers and how to manipulate them. © 2007 Paul Dawkins 1 http://tutorial.math.lamar.edu/terms.aspx College Algebra Integer Exponents We will start off this chapter by looking at integer exponents. In fact, we will initially assume that the exponents are positive as well. We will look at zero and negative exponents in a bit. Let’s first recall the definition of exponentiation with positive integer exponents. If a is any number and n is a positive integer then, a n = a × a × a ×L × a 14243 n times So, for example, 35 = 3 × 3 × 3 × 3 × 3 = 243 We should also use this opportunity to remind ourselves about parenthesis and conventions that...
