(x^2+x+2)+(2x^2+3x+7) = ?

you mean like that?

Answer 9

yes

Answer 10

except not as many steps.

Answer 11

(5x-7) + (2x + 3) = ?

Answer 12

more like this : 8x² – 5x – 2 + 7x – x² + 3
I solved this one already but this is just an example

Answer 13

oh yeah thats a great one sleepy

Answer 14

tbh khanacademy probably has a problem generator
instead of me trying to come up with random questions out of my head xD

Answer 15

that one works though thats actually perfect.

Answer 16

how would i solve this (5x-7) + (2x + 3) except with it like (5x-7+ 7x^3) + (2x + 3 + 5x^2)

Answer 17

just add up thing things that have the same letter things

5x + 2x = 7x

Answer 18

for instance i have this one to do ... (2𝑥^2 +𝑥+5 +(3𝑥^2 +4𝑥+1)

Answer 19

yeah that one is easy this one is a it tougher.

Answer 20

"add like terms"

2x^2 + 3x^2 = 5x^2

Answer 21

and 5 + 1 is 6 so?

Answer 22

im guesssing 5x^2 + 6 + 4x= ?

Answer 23

alright final one

Answer 24

not quite

Answer 25

don't forget the 4x + x = 5x

Answer 26

Answer 27

i got it now but can we do one with some minuses in it

Answer 28

Answer 29

Answer 30

4x^2 - 7x + 1 - x^2 + 3x - 9

Answer 31

7x + 3x = 10x

Answer 32

see the negative?

Answer 33

-7x + 3x

Answer 34

oh so 4x

Answer 35

or -4x

Answer 36

negative still

-4x

Answer 37

Answer 38

4x^2 + 2x -1) x ( 3x^3 – x + 4)

Answer 39

you there @sleepyhead314 ?

Answer 40

(a + b - c)*(x - y + z) = a*x + a*(-y) + a*z + b*x + b*(-y) + b*z + (-c)*x + (-c)*(-y) + (-c)*z

Answer 41

how does this help?

Answer 42

sorry, that came out messy >,<it's just a longer distributive property
