Question

4w ²+7w-7+5w²-6

Answer 1

@xapproachesinfinity

Answer 2

okay
so we need to add like terms!

Answer 3

\(4w^2~with ~5w^2~ and ~ 7w ~has~no~company~ we ~go ~to~-7~ goes~with~-6\)

Answer 4

what is 4w^2+5w^2
think about it this way
4 chairs + 5 chairs so how many chairs i got

Answer 5

9

Answer 6

right! so we have 9w^2

Answer 7

what is -7-6?

Answer 8

-13

Answer 9

correct!
now we have everything \(9w^2-7w-13\)
we cannot do anything to -7w thiis has no like term with it

Answer 10

this is as far as you go for simplifying this

Answer 11

Pop it in the blender so you get two answers or real roots.

Answer 12

If the equation doesn't have real roots, you get the equation @xapproachesinfinity gave.

Answer 13

she is not looking for roots so don't confuse her
i think she just started working this

Answer 14

Do you get it @Selena2345

Answer 15

whats the answer ? @xapproachesinfinity

Answer 16

I'm not confusing her, I'm just saying. @Selena2345 , disregard whatever I wrote.

Answer 17

the answer is \(9w^2-7w-13\)

Answer 18

you just add like terms and simplify that's all

Answer 19

16w-13

Answer 20

why?

Answer 21

what

Answer 22

you can't add 9w^2 to -7w there two different quantities
see that they have different powers

Answer 23

they will stay that way \(9w^2-7w-13\) you can't do more than this!

Answer 24

the answer is -13

Answer 25

No! the answer is an expression
this \(9w^2-7w-13\) do you see what i'm saying

Answer 26

What @xapproachesinfinity said x1000 times. What's the answer in the book?
