3. Simplify the expression.
9xy2 – 11xy2
I combine like terms
9xy^4 rounded to 66xy
66xy/-11 = -6
I have no clue to how to solve this.

Is the question:

$\sf\Large 9xy^2-11xy^2=?$

anonymous · Answer

Yes

abdullahm · Answer

we can factor out the $\sf\Large xy^2$ to make it easier. :)

anonymous · Answer

Alright.

anonymous · Answer

So it's  9 -11  = 3?

abdullahm · Answer

Use a calculator

9 - 11 = -2

abdullahm · Answer

It seems like you have slight difficulties in addition/subtraction when the answer is negative...

anonymous · Answer

Hehe yeah

anonymous · Answer

so It's xy = -2?

abdullahm · Answer

one sec

abdullahm · Answer

$\sf\large 9xy^2-11xy^2= xy^2(9-11)=xy^2(-2)=-2xy^2$

anonymous · Answer

I don't think i'm going to remember that with out going over it a lot of time.
Thanks a 
lot though i appreciate you putting up with me

abdullahm · Answer

just remember this, it will make it easier

$\sf\Large ab + ac = a(b+c)$

anonymous · Answer

Alright, i'll try to keep that in mind.

abdullahm · Answer

if you forget it, it's called the distributive property.

and I just switched it so that it would be helpful for this question.

The distributive property actually says:

$\sf\Large a(b+c) = ab+ac$
