Scribe Post
Hello Christian here for the scribe post.



The first thing we did is mental math while playing BINGO. The winner of the game is Alisa for the second time. The mental math was about Multiplying Polynomials.

ex.

(3x²y²) (6abx²z³)
First step is you multiply the number coefficients = (3)(6)= 24 And then multiply the variables = (x²y²) (abx²z³)= abx³y²z³
put the two together= 24abcx³y²z³

The next thing we did is we went over to our tests about Adding and Subtracting Polynomials.

Then we did question number 16 in the paper that Miss Nicholson gave us about Algebraic Problems about Perimeter.

Ex.



So the first thing you do is add both sides.
-7x²+9
2x²-3
-----------
 -5x²+6
Then subtract the answer to the perimeter.
-20x²-10 = -20x²-10
 - -5x² +6 =+ 5x² -6
 --------------------------------
the answer is -15x² -16

and lastly we had the bag and we put money for donation now we have $66.00 :)

    Wow Christian! You've definitely taken our scribe posts to the next level!

    Great idea to include links to websites that will allow the class to practice the concepts! We haven't arrived at multiplying polynomials yet (just monomials), but we certainly will!

    I also think it was a great idea to draw out the triangle for the perimeter question the way that you did... did you use paint?

    Also impressive that you came up with your own examples!

    How do you think you could have organized the multiplying example to make it even easier to read?

    Keep it up!
