Algebra Essentials Practice Workbook with Answers
Chris McMullen, Ph.D.
Practice solving equations for x.
The problems in the last chapter have two unknowns: x and y.
Plenty of practice exercises
Each chapter contains ample practice exercises.
Three keys to building fluency in algebra are: practice, practice, practice.
Build confidence
The answer to every problem is included.
When you get the right answer, this helps to build confidence.
If you get an answer wrong, study your solution, rework the problem, or review the examples so that you can learn from your mistake.
The answers are in standard form: fractions are reduced, denominators are rationalized, and perfect squares are factored out of square roots.
Topics include:
combine like terms to isolate the unknown
linear equations with fractional coefficients
simple quadratic equations (factor to get all possible solutions)
factor quadratic equations
use the quadratic formula
cross multiplying (sometimes resulting in a quadratic)
systems of equations (solve by substitution or simultaneously)
Develop fluency in solving equations for the unknown(s).
Isolate the unknown
isolate the unknown by separating variables and combining like terms
one chapter has fractional coefficients
Quadratic equations
first solve simple quadratics
practice factoring the quadratic equation
practice using the quadratic formula
Cross multiply
cross multiply and distribute
some result in quadratic equations
Systems of equations
solve two equations in two unknowns
use substitution or solve for two unknowns simultaneously
Build fluency with essential algebra skills through practice.
Ideal for students who could benefit from more comprehensive algebra coverage, detailed explanations, and more fully solved/explained examples. Excellent for students who are learning algebra.
Excellent preparation for algebra, finishing with a taste of beginning algebra skills. Includes the order of operations.
Intended for students who need a lot of practice with combining like terms and factoring. Also includes distributing, the FOIL method, and isolating the unknown.
Focused solely on the algebra of word problems.
Focused on solving 2 equations with 2 unknowns or solving 3 equations with 3 unknowns using different methods, including Cramer's rule.
