This one is insanely important when working with algebraic expressions. The distributive property basically says this:
However, the distributive property does not work when the variables inside the parentheses are being multiplied or divided.
Let's go through an example very carefully:
By applying the distributive property, we can multiply each term inside the parentheses by 4. This is called "distributing."
Since 12x and 4 are not like terms, this is as far as we can go with the problem.
What about subtraction? Let's look at a subtraction problem using two different methods.
|Method 1 |
Leave as Subtraction
|Method 2 |
Add the Negative
Either way, we get the same answer: -14 + 4x. What a relief.
