How to factor out the GCF of a binomial
Elementary Algebra Review Part 5
 How do you evaluate variable expressions with given values of variables?
 How do you evaluate x  y + z when x = 2, y = 3, and z = 4?
 How do you evaluate z  x^3 when x = 2 and z = 4?
 How do you evaluate (x  y)/(z + 2) when x = 2, y = 3, and z = 4?
 How do you evaluate (x^2  z)/(z  3x) when x = 2, y = 3, and z = 4?
 If x = 56 degrees, and x and y are complementary angles, how do you find angle y?
 If x = 56 degrees, and x and y are supplementary angles, how do you find angle y?
 Is p + n always positive if p is positive and n is negative?
 Is p  n always positive if p is positive and n is negative?
 Is n  p always positive if p is positive and n is negative?
 How do you know if adding and subtracting positive and negative numbers will always result in a positive number?
This lesson does more with plugging values into variable expressions and evaluating them using order of operations. Every step is explained very clearly again. A couple of examples are done finding angle measures from words as well as determining whether adding and subtracting positive and negative numbers will always result in a positive number.
