We will have a test on chapter 9 on 3/3.

Homework for this week:
p. 410 10 and 11(these are the adding and subtracting problems shown vertically)BE SURE to change the signs on all the terms of the second polynomial when you are subtracting. You can do all adding and subtracting polynomials vertically or horizontally – it is your choice.
P. 410 13, 14 and 15
The answers to these are not in the back of the book , so I will attempt to answer them at the bottom of this email. It is impossible to type an x squared on my keyboard, so answering these will be somewhat of a challenge in that regard.

p. 421 2, 8 and 10
p. 426 1,2,7and 9 On #7 ,you may use the shortcuts we talked about in class or you can multiply them out using FOIL

I am not going to assign the dividing problems yet, but I think it would be fun ðŸ™‚ if you tried one just to see if you can remember how we did these boogers in class! Try p.435 6a ! Check your answer in the back of the book.

10a) 5x+5
b)8x-2y
c)6xsquared -10x
d) 4xsq.-3
e) x to the 4th power +10 xsq – 2x-2

***xsq means x squared

11a)7x -12
b)y
c)xsq-4
d)-xsq+5x-15
e)2xcubed – xsq+2

13)2xsq+2
b)14x-10y
c)xcubed+xsq+x-1
d)3xcubed+5xsq+4

14a)5x-5ysq
b)26
c)3xsq-4x+1
d)x+2y+7

Let me know if you have questions,
Mrs. A
