Students are proud of their creative work on their page and suddenly begin pulling out their notes sheets consistently to review, show them off, and reference them as a study guide. Added bonuses include relaxation, coordination, and a boost in problem solving skills.
To add or subtract rational expressions with unlike denominators, first find the LCM of the denominator. The LCM of the denominators of fraction or rational expressions is also called least common denominator , or LCD. Write each expression using the LCD. Make sure each term has the LCD as its denominator.

Solving Linear Systems of Equations Using Substitution Include an explanation of the graphs - one solution, no solution, infinite solutions Examples: 2x + 4y = 4 y = x - 2 x + 3y = 6 2x + 6y = -12 2x - 3y = 6 4x - 6y = 12 Show Step-by-step Solutions
Notes — Writing Linear Equations in Slope-Intercept Form [j Identify the initial value (y-intercept) from a table, graph, equation, or verbal description. Use the slope and y-intercepts to write a linear function in the form y = mx+ b from any representation (table, graph, or verbal description). Graph a linear equation given an equation.
We must do the same thing when adding or subtracting rational expressions. The easiest common denominator to use will be the least common denominator, or LCD. The LCD is the smallest multiple that the denominators have in common. To find the LCD of two rational expressions, we factor the expressions and multiply all of the distinct factors.
