Course Overview
Students are able to gain credit if they have previously completed this course but did not successfully earn credit. For each unit, students take a diagnostic test that assesses their current knowledge of fundamental content. The results of these tests help students create individualized study plans. This is the second semester of MTH126.
In this course, students review the tools of algebra. Topics include the structure and properties of real numbers; operations with integers and other rational numbers; square roots and irrational numbers; linear equations; ratios, proportions, and percentages; the Pythagorean Theorem; polynomials; and logic and reasoning.
SEMESTER TWO
Algebra I B, Unit 1: Relations and Functions
A solar cell is a little machine that takes in solar energy and puts out electricity. A mathematical function is a machine that takes in a number as an input and produces another number as an output. There are many kinds of functions. Some have graphs that look like lines, while others have graphs that curve like a parabola. Functions can take other forms as well. Not every function has a graph that looks like a line or a parabola. Not every function has an equation. The important thing to remember is that any valid input into a function, results in a single result out of it.

Unit 3: Working with Polynomials
Just as a train is built from linking railcars together, a polynomial is built by bringing terms together and linking them with plus or minus signs. Basic operations on polynomials work the same way as adding, subtracting, multiplying, and dividing numbers.
 Foundations

Unit 4: Factoring Polynomials
A polynomial is an expression that has variables that represent numbers. A number can be factored, but what about a polynomial? Sometimes yes and sometimes no. Finding ways to write a polynomial as a product of factors can be quite useful.
 Foundations

Unit 5: Quadratic Equations
Solving equations can help answer many kinds of problems. Linear equations usually have one solution, but what about quadratic equations? How many solutions can a quadratic equation have and what do the solutions look like?
 Foundations
 Solving Perfect Square Equations
 Completing the Square
 The Quadratic Formula
 The Discriminant
 Solving Quadratic Equations
 Equations and Graphs: Roots and Intercepts
 Applications: Area Problems
 Applications: Projectile Motion

Unit 6: Rational Expressions
A fraction always has a number in the numerator and in the denominator. However, those numbers can actually be expressions that represent numbers, which means you can do all sorts of interesting things can happen with fractions. Fractions with variable expressions in the numerator and denominator can help solve many kinds of problems.
