Take your time

I have really bad cameras :/ can you see this one better?

- ElisaNeedsHelp

it would just be a pain to type everything

- GabeBae

Is it
(-6v^2 + 2v - 3) + (6v^2 + 5v +4)?

- ElisaNeedsHelp

no, its (-v^2+2v-3)+(6v^2+5v+4)

- GabeBae

Okay

- GabeBae

To make it simplier for you line them up with the like terms
So it would be
-V^2 +2v -3
6V^2 +5v+4
-----------
Then you would multiple like you would with a normal multiplication question

- ElisaNeedsHelp

I knew I forgot. Good thing I asked to check my answer! Thank you

- GabeBae

What did you get?

- ElisaNeedsHelp

-12v^4+10v-12

- ElisaNeedsHelp

I always doubt with the exponents

- GabeBae

Let me try it

- ElisaNeedsHelp

ok thank you

- GabeBae

When I multiplied it all I got -6v^4 + 7v^3 + 33v^2 + 23v - 12

- FibonacciChick666

why did you multiply? It's addition yea?

- FibonacciChick666

\((-v^2+2v-3)\color\red{+}(6v^2+5v+4)\)

- GabeBae

Oooh right

- GabeBae

My bad

- FibonacciChick666

same thing goes for Elisa

- ElisaNeedsHelp

Lol bind blown

- FibonacciChick666

nice foiling, but unnecessary :)

- GabeBae

You would still line them up and add them that way so it would be easier to understand

- ElisaNeedsHelp

omg im confused

- GabeBae

Okay I got my answer
I can explain

- FibonacciChick666

I also believe in complete sentences like you did in your work, but next time, try not to do it all in one step. It increases chances for error

- FibonacciChick666

why don't you try to simplify now elisa

- FibonacciChick666

here is the problem again (-v^2+2v-3)+(6v^2+5v+4)

- ElisaNeedsHelp

Im confused now

- FibonacciChick666

alright, where

- GabeBae

|dw:1446324599314:dw|

- GabeBae

I don't think you need to add the exponents together

- ElisaNeedsHelp

Oh so its just adding like that

- FibonacciChick666

if you want a walkthrough, I can assist with that

- GabeBae

That's why I told you to line them up so you wouldn't get confused

- ElisaNeedsHelp

No its okay I understand now, I multiplied when I shouldve added :/

- FibonacciChick666

well, I really hate that particular writing style. You want to write in full sentences. Not to mention, grouping like terms and simplifying helps for future math

- ElisaNeedsHelp

Thanks lol to both of you

- FibonacciChick666

Here would be my approach-although both are correct

- GabeBae

mhm?

- FibonacciChick666

So full sentences, and it is mathematically provable using properties \[ (-v^2+2v-3)+(6v^2+5v+4)=\\=-v^2+2v-3+6v^2+5v+4\\= -v^2+6v^2+2v+5v-3+4\\= 5v^2+7v+1\\\]

- ElisaNeedsHelp

thank you :)
