Factoring polynomials became much easier for me when I realized that I was working with numbers in base x! X to the zero power correlates with the ones place in base ten, X raised to the power of 1 correlates to the tens place, X-squared to the hundreds place, and so on. Suddenly I could use factor trees! Play around with it, and if you have questions, let me know.

Polynomial Exponents Lessons The previous lesson explained how to simplify exponents of a single term inside parentheses, like the problem below. (x3y4)5 This lesson covers how to simplify exponents on parentheses that contain a polynomial (more than one term), like the problem below. (x3 + y4)2 Because the two terms inside parentheses are not being multiplied... read more

Introduction To Factoring A composite number is a number that can be written as the product of two positive integers other than 1 and the number itself. For example: 14 is a composite number because it can be written as 7 times 2. In this case, 7 and 2 are called factors of 14. A composite expression is similar in that it can be written as the product of two or more expressions. For example:... read more
