The second semester set of this algebra software is appropriate for second semester algebra 1 students, first semester algebra 2 students & college algebra students. Algebra help is available from each practice question.
Chapter 5: Rational Expressions (Algebraic Fractions)
Performing operations of addition, subtraction, multiplication, and division on fractions is always a challenging topic for students. This program reviews the basics operations on numerical fractions before advancing to operations on algebraic fractions. Also, included in this program are negative powers and scientific notation. The study of algebraic fractions concludes with a word problem section using the learned material from the body of the program.
Chapter 6: Roots, Radicals, and Complex Numbers
Follow the progression from simplifying roots and radicals, through the properties of radicals. Practice sums of radicals and learn about binomials by rationalizing denominators and applying FOIL (multiplication of binomials). Solving radical equations are practiced. A thorough discussion and practice involving rational and irrational numbers is followed by an in-depth study of imaginary and complex numbers. The problem solving section and test conclude this program.
Chapter 7: Quadratic Equations
Begin the study of quadratic equations by learning the ever-important method of "completing the square"... followed by Algebra's most eloquent formula, the "Quadratic Formula" -- practice, practice, practice the important use of the quadratic formula! Learn about the Discriminant and what it reveals about the nature of the solutions (are they real, non-real, rational, irrational). Use the quadratic formula and other methods to solve a variety of quadratic equations from simple to complex. Learn to graph and analyze quadratics -- learn what to look for -- the key elements which comprise a good and accurate graph (the vertex, the axis of symmetry, the x-intercept(s), the y-intercept(s). Apply the sum and product rules for finding a quadratic equation given the roots of the equation. Conclude with word problems and a test.
Chapter 8: Variation and Advanced Polynomial Equations
Start by reviewing the basics of ratios and proportions. Then, move on to the concepts of direct and inverse variation, for which a multitude of "real life" problems exist and are practiced in the word problem section. Long division is covered step-by-step. Use the quadratic formula within equations beyond quadratics, the power of the Remainder Theorem is explained and practiced before moving on to the Factor and Rational Root Theorems. The conjugate root theorem is used to solve higher degree equations which contain non-real roots. Descartes' Rule of Signs tops off the algebra software lessons on advanced polynomial equations. Conclude with problem solving and a test. These advanced polynomial equation topics are very important for algebra 2 students, pre-calculus students and college algebra students. This software will coach you with step-by-step algebra help and encouragement.
