Question

3x^2 – 2x – 1 + 9x + 2x^2 - 3

Answer 1

hurry i need help

Answer 2

Combine Like Terms

Answer 3

/ok

Answer 4

can you show me the steps please

Answer 5

not the answer

Answer 6

like terms; examples:

\(\large\color{black}{ \displaystyle 2x^2+3x^2=5x^2 }\)

\(\large\color{black}{ \displaystyle 9x^w-8x^w=1x^w=x^w }\)

\(\large\color{black}{ \displaystyle 2y-5y=-3y }\)

\(\large\color{black}{ \displaystyle 14+13=27 }\)

Answer 7

those are examples of the terms you can combine (their coefficients - the numbers in front of the variable - don't matter. And the like term is defined if there is a same variable and it is raised to the same power.)

Answer 8

where did you get 8x?

Answer 9

but you can NOT combine (examples)

\(\large\color{red}{ \displaystyle 3x^4+2x^3 }\)
(although variable is same, the powers of x are NOT the same)

\(\large\color{red}{ \displaystyle 2x^p+3a^p }\)
(although the powers of the variable are the same (power of p), because variables are NOT the same.)

\(\large\color{red}{ \displaystyle 5+3x }\) (one term contains variable, the other term does not)

Answer 10

@some.random.cool.kid
I didn't get 8x. these that I posted are just examples.

Answer 11

can you make the examples for my equation?

Answer 12

i want to know how the equation would be set without any answer @SolomonZelman

Answer 13

@sleepyjess can you help me too

Answer 14

ok, I will highlight each like term in a particular color.

Answer 15

k thanks

Answer 16

\(\LARGE\color{black}{ \displaystyle \color{red}{3x^2} \color{blue}{- 2x} \color{green}{- 1} \color{blue}{+ 9x} \color{red}{+ 2x^2} \color{green}{- 3} }\)

Answer 17

so is it 5x^2 - 7x - 2?

Answer 18

Answer 21

@Data_LG2

Answer 22

-1-3 is?

Answer 23

idk

Answer 24

-2

Answer 25

-4

Answer 26

\(\LARGE\color{black}{ \displaystyle \color{red}{3x^2} \color{blue}{- 2x} \color{green}{- 1} \color{blue}{+ 9x} \color{red}{+ 2x^2} \color{green}{- 3} }\)

re-write in order

\(\LARGE\color{black}{ \displaystyle \color{red}{3x^2} \color{red}{+ 2x^2}\color{blue}{- 2x}\color{blue}{+ 9x}\color{green}{- 1} \color{green}{- 3} }\)

Answer 27

is this better?

Answer 28

i solved it already

Answer 29

was i correct

Answer 30

its above

Answer 31

no, it is not correct

Answer 32

I wrote it an order better to see just now

Answer 33

5x^2 - 7x + -4 =?

Answer 34

-2+9=-7 or +7?

Answer 35

thats the answer when i combined them now i must solve this

Answer 36

-2 + 9 = -7 or +7 ?

Answer 37

its 7x

Answer 38

yes

Answer 39

\(\LARGE\color{black}{ \displaystyle \color{red}{3x^2} \color{red}{+ 2x^2}\color{blue}{- 2x}\color{blue}{+ 9x}\color{green}{- 1} \color{green}{- 3} }\)

\(\LARGE\color{black}{ \displaystyle \color{red}{5x^2}\color{blue}{+7x} \color{green}{- 4} }\)

Answer 40

i solved that part already so from there whats next

Answer 41

this is it

Answer 42

you don't need any work, you combined all the like terms, and now this polynomial is written in a simple form.

Answer 43

simplest* form

Answer 44

yw

Answer 45

thank you very much i have one mor

Answer 46

can i put it @SolomonZelman

Answer 47

can you put it?

Answer 48

8x^2 – 5x – 2 + 7x – x^ + 3

Answer 49

oh, another question? I thought you were referring to the answer to this question. Sure, go ahead and post it here.

Answer 50

\(\large\color{black}{ \displaystyle 8x^2 – 5x – 2 + 7x – x^2 + 3 }\)
like this?

Answer 51

ok next is 12x right

Answer 52

because 5x and 12x combined

Answer 53

7x*

Answer 54

and 5 because of 2 + 3

Answer 55

how many x^2 is there?

Answer 56

two

Answer 57

\(\large\color{black}{ \displaystyle 8x^2- 5x - 2 + 7x - x^2 + 3 }\)

\(\large\color{black}{ \displaystyle 8x^2 - x^2- 5x + 7x - 2 + 3 }\)

Answer 58

12x and 5

Answer 59

-5+7=12 ??

Answer 60

or does -5+7 =2 ?

Answer 61

2

Answer 62

@SolomonZelman what about the x^2 - 8x^2

Answer 63

2x and 5 now what about the 8 part? @SolomonZelman

Answer 64

hurry

Answer 65

8x² – 5x – 2 + 7x – x² + 3
8x² – x² + 7x – 5x – 2 + 3
7x² + 2x + 1

Answer 66

thanks
