Adding and Subtracting Polynomials
Hi every one !
i am scribe post today and need to tell you guys what did we do in classtoday in class Ms. Nicholson pass to us a bag for the world vision's gift catalogue and we put carpel of dollar that we can put.
Then she give us a quiz of Subtracting Polynomial and adding polynomial
(2(2x)+2x+5) - (2(5x) - 7x +4) first be for we do this. When we subtracted one polynomial from another we add the additive inverse ( opposite) of the polynomial that's being
Subtracted
Example: (2(2x)+2x+5)
(2(-5x) + 7x-4)
=(2(-3x)+9x+1
Adding
Example: (2(3y) - 8y+3) + (2(2y)+8y-9)
(2(3y) - 8y+3)
+ (2(2y)+8y-9)
=(2(5y)-6

Well done Yassir! You remembered to add examples to your post to make it more meaningful to your classmates. You are also correct about the difference between adding and subtracting polynomials.
I see that you were not quite sure how to format the exponents on your x-squared terms. One way is to use the "^" key (shift+6). For example, 8x-cubed would be 8x^3.
There is also a link on the right side of the blog that explains how to do it with HTML coding. Take a look at it! Who would like to edit this post for bonus marks on the next test??
