How do you add and subtract functions?

Here's an example of adding two functions

We basically add the expressions like normal. There are 3 pairs of like terms

==========================================================

Now let's say we wanted to subtract those two functions.

Notice in the fourth line, the negative distributes to each term inside the parenthesis. This is because we're subtracting off and also subtracting off (i.e. adding ) and also subtracting off all from f(x).

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
