Summary of the procedure for factoring by grouping.
Demonstration of factoring a polynomial with three terms that share a common factor: 35x 15y - 20z.
Two different ways to write an algebraic equation for the same word problem involving rate, time, and distance are compared.
Three different approaches to solving the same practical problem are demonstrated. Two approaches using one variable and a two-variable system all produce the same solution to the question of how many balcony seats and how many floor seats can be so...
Solving a problem in which both denominators are quadratic trinomials is demonstrated.
A problem is presented to practice solving an equation using the least common denominator to get a quadratic equation.
Finding the square root of a decimal is discussed, noting that any decimal that does not have an even number of places after the decimal cannot have an exact square root.
Be thorough when checking for common factors, especially when factoring by inspection. You have not factored completely until no common factors remain.
