Algebra - Mixed Practice (Up to Rational Expressions)
This is a fairly lengthy unit in most algebra textbooks. In these worksheets we'll review much of the content up to this point in the curriculum, and also cover the following topics: reducing algebraic fractions; multiplying and dividing algebraic fractions; finding least common multiples of algebraic expressions; adding and subtracting algebraic fractions; complex fractions; solving fractional equations.
Some algebra one curricula do not include fractional equations that result in quadratics. However, since we have already completed the quadratic unit, we will include some quadratic fractional equations here. Those will be notated below, so if you don't want to have your students do those problems (or if you want them to be "bonus"), you may do so.
- Finding LCMs
- Converting phrases to algebraic expressions
- Reducing algebraic fractions
- Combining like terms
- Multiplying and dividing numeric fractions
- Multiplying and dividing fractions
- Solving linear equations
- Factoring polynomials
- Finding the LCM of algebraic expressions
- Solving quadratic equations
- Adding and subtracting numeric fractions
- Adding and subtracting algebraic fractions
- Solving word problems
- Complex fractions
- Simplifying and factoring
- Solving fractional equations (the last three problems are quadratics)

Mixed Practice 7.3
Solve the equations
- 3x - 12x = x + 15
- 5(x - 12) = 3(x + 4) + 10
- x(x + 1) = (x - 1)(x - 2) + 20
- 3x + 10 - 2(x + 1) = 15
- 2(x - 3(x - 1)) + 2 = 32 - 2x
Factor the following expressions
- x2 - 18x + 17
- 3x2 - 12
- 4x2 - 4xy + y2
