I hate algebra 2. like alot

OpenStudy (anonymous):

OpenStudy (nory):

Add the expression for f and the expression for g. What do you get?

OpenStudy (anonymous):

8x and 2x

OpenStudy (anonymous):

correct?

OpenStudy (nory):

I'm confused. How did you get 8x and 2x?

OpenStudy (anonymous):

3 +5 and x^2 is 2x

OpenStudy (anonymous):

i mean i know a little bit.

OpenStudy (nory):

I see what you did, and you did the right thing. But you can't add 3x and 5. That's just not allowed.

OpenStudy (nory):

The right answer would be x^2 + 3x + 5.

OpenStudy (anonymous):

well how do you add them? or is it 5x +5?

OpenStudy (nory):

You don't. You just write 3x + 5.

OpenStudy (anonymous):

what about the x squared?

OpenStudy (nory):

It's like, if I had 5 boxes and 3 books, I wouldn't be able to add them. I mean, I would have 8 objects, but you can't just say I have 8 boxes or 8 books.

OpenStudy (nory):

The x squared too.

OpenStudy (nory):

does that make sense?

OpenStudy (anonymous):

face palm

OpenStudy (nory):

It's okay

OpenStudy (nory):

At least you added them

OpenStudy (anonymous):

okay so with that being answer above how do i solve

OpenStudy (nory):

You don't. x^2 + 3x + 5 is your answer.

OpenStudy (anonymous):

oh. so exponents cant be added to variables?

OpenStudy (nory):

No. Like in the example I gave above. Does that make it a little clearer?

OpenStudy (anonymous):

Yeah its just going to take some getting use too. i just switched from geometry to algebra

OpenStudy (nory):

No problem. I'm about to switch from algebra to geometry...

OpenStudy (anonymous):

Good luck.

OpenStudy (nory):

thanks. same to you.

OpenStudy (anonymous):

:)
