I'm waiting for more students to join the site.
Please click on the Deltamath link and create an account.
The code is 494786.
In the meantime, get caught up on your other class assignments!
The distributive property questions on the delta site will have different levels of difficulty.
Do your best. Try the more difficult ones, also.
The more difficult problems will have exponents.
Try them. Remember, that when putting variables together via addition or subtraction, they have to be exactly the same.
THE NOTES BELOW SHOULD HELP YOU WITH THE DISTRIBUTIVE PROPERTY PROBLEMS THAT HAVE EXPONENTS IN THEM...
2
X + X cannot go together. They are different. Just like X + Y is different. X and Y are cats and dogs...
2
X and X are like two different types of dogs (dobermans and chihuahuas). DO NOT FORCE THEM TOGETHER when adding or subtracting.
However, they can be multiplied together. Which you may encounter in the distributive property problems.
When multiplying the same variables with different exponents, you add the exponents.
2 3
X * X = X ...
We haven't done enough of this, but try those problems when you encounter them.
Remember, you are still using SNL when multiplying; Signs, Numbers, and Letters...
Example:
2
-3X * 6X=
Sign = negative (there's an odd amount of negatives)
Numbers= 18 (3 * 6=18)
3 2 3
Letters = X (X * X = X ) ... If there is no exponent for the variable, there is a 1 there.
Put all three together...
3
Answer= -18X
2 2 1
Lastly... X * X is the same as X * X .
The books, teachers, and tests almost never use the 1 if the exponent is 1. It's just understood to be there. The same as they don't put the 1 in front of variables. It may help you to put the 1 there when dealing with problems that have exponents.
WE HAVEN'T DONE MUCH WITH EXPONENTS. WE'LL DO MORE AS WE GO. TRY THE EXPONENT PROBLEMS. DON'T GET DISCOURAGED IF YOU MESS THEM UP... HOWEVER, THESE NOTES SHOULD BE A START TO HELP YOU.
