## Algebra - Mixed Practice (Up to Factoring)

In this set of worksheets, we review content up to factoring of algebraic expressions.

New content includes difference of squares, perfect square binomials, and general quadratics. The last worksheet also includes problems which are solved by factoring a quadratic.

Other content reviewed includes solving word problems, finding LCM and GCF (which will be especially useful in the next unit when we start working with algebraic fractions), and manipulating polynomials.

Note that multiple step factoring problems are reserved for the last worksheet in this set.

**Worksheet 5.1**

- LCM and GCF
- Fraction manipulation
- Word problems
- Factoring difference of squares and perfect squares

**Worksheet 5.2**

- Multiplying and dividing monomials
- Simplifying algebraic expressions
- Factoring difference of squares and perfect squares
- Factoring general quadratics

**Worksheet 5.3**

- Simplifying expressions with positives and negatives
- Multiplying polynomials
- Factoring - multi-step problems
