Journal entry #25. 11/1/10 Today we learned (practiced) how to solve and identify polynomials. The problems we solved had some funky figures (shapes) in them so i'll write down the expression ones. #3. (3x2 + 2x-2) + (-2x2+5x+5)= (3x2 + 2x-2-2x2)=(x2+7x+3) *note that a polynomial is a monomial or a sum of monomials.
@Evelyn, there were notes you had to take. Maybe someone will let you copy them tomorrow. You can also preview the lesson by reading the journal entries.

Journal entry Today in math we learned about identifying and adding polynomials. Example (3x2+2x-2)+(2x2+5x+5)= 5x2+7x+3 You can solve this in either verical or horizontal. I used the horizontal way.
Journal Entry 11/1/10 Today we learned about polynomials. We learned how to combine/add the polynomials. For example: (3x^2+2x-2)+(-2x^2+5x+5)=x^2+7x+3
Today we learned how to find the area of odd shaped figures and how to add them. we also learned how to add polynomials Ex. horizantal (3x^2+2x-2)+(-2x^2+5x+5) = x^2+7x+3 or vertical 3x^2+2x-2 -2x^2+5x+5 _____________ x^2+7x+3
oh! i remeber that pic! yay! 2 of my fingers r in it! btw...ms gladden just emailed me and said that she just finished grading per 1's tests, and she'll post ours on the blog later.
Journal entry #25 november 11,2010 Today in class we took notes about finding the area polynomials. You had to combine like terms. some examples are: 3x2+2x-2 x2<-exponent -2x2+5x+5 =x2+7x+3
Today in math class we went over how to find the area of different shapes using polynomials. Mr. Gerson also taught us about using the horizontal and vertical methods for simplifying polynomials. Personally, i prefer the horizontal method just because I am used to it, but both methods work perfectlly well.
Today I learned how to solve and identify polinominals. Basically, just add together like terms as if you would to any other addition problem. At first, I didn't understand how to solve the questions, but I failed to write the exponents as exponents in the homework. My bad.

i was absent today, did we have to take notes during 3rd?
if we did can someone post them please and thanks!

do we have to justify on 5-15???
and on 17 and 19?
ok then thanks!

No justifications, right?

yes u have to justify but on the word problems it's not really possible

how do i superscript my exponents?
Today we learned how to find the area of odd shaped figures and how to add them.
we also learned how to add polynomials Ex.
horizantal (3x^2+2x-2)+(-2x^2+5x+5)
= x^2+7x+3
or vertical 3x^2+2x-2
-2x^2+5x+5
_____________
x^2+7x+3

i have question mark cuz they're not a paragraph long...so idk if i should count it
For number 33 on page 234, do we substitute for n to show how it's commutative? And do we do both examples seperately or add them?
idk...it was VERY confusing! i just made it commutative and thats it...
oh! i remeber that pic! yay! 2 of my fingers r in it!
btw...ms gladden just emailed me and said that she just finished grading per 1's tests, and she'll post ours on the blog later.
okay. wait, how did you make it commutative exactly? like did you add both things?
wat is the first step in 3(5-x)<or equal to 2(x-9)
distributive property
You have to copy the problems down.
@Natasha: If you counted Tetsu's, then you have to count Matthew's and Rebecca's, or don't count any of them.

Mr Gerson, will we have another test before Novemeber 19?
Also... will there be any extra credit soon?

x2<-exponent -2x2+5x+5
=x2+7x+3
@Eric oops haha i didn't c that sorry :3

@Marcus Mr. Gerson doesn't give out extra credit...
Oh... ok.Thanks!
WMD 2010 was extra credit.
there was no WMD this year
today we learned how to identify polynomials
eg.
3x+2x+1
5x+9x+3
add them all together
=19x+4

thats sort of late marcus. i think it counts but u should of done it earlier
