Expression in expanded form |
An expression that is written as sums (and or differences) of products whose factors are numbers or variables (3x + x) |
|
|
simplifying Expanded form |
simplify only if there are like terms. Remember, like terms have variables that are exactly the same |
|
|
Expanded form, Distributive property |
Expanded= x + x + x(3x) + x + x + x + x (4x) 4x + 3x = 7x |
|
|
Subtraction + Distributive Simplifying |
y + y + y + (-y + -y)= 3y 2y |
|
|
Any order, any grouping Property |
