Question

Is this simplified correctly?

(6x - 2x^2 + 3) - (4x - 3 - 3x^2)
6x - 2x^2 + 3 - 4x + 3 + 3x^2
6x - 4x - 2x^2 + 3x^2 + 3 + 3
2x + x^2 + 6

Answer 1

@superhelp101 ?

Answer 2

okay so for this (6x - 2x^2 + 3) - (4x - 3 - 3x^2) the negative between the two parenthesesis suppose to be change to a positive i believe, so it'll look like this
6x - 2x^2 + 3 + 4x + 3 + 3x^2

Answer 3

I don't think so. I didn't do that to my other problems.

Answer 4

oh but no i see what you did now! that part is correct. let me look at the rest

Answer 5

because a + and a - is a -

Answer 6

ok so now you get 6x-2x^2+3-4+3+3x^2
then you have to combine like terms do you know how to do that?

Answer 7

you add up all of the ones with the same terms like 2x^2+3x^2 to get 3x^2
and add up all the other numbers without the terms and you will get -1
and also add 6x
the add them all together the answer would be 3x^2+6x-1

Answer 8

No, no, something's wrong here.

Answer 10

I want to explain but not give the answer, how do I do this....

Answer 11

I already did the answer, first tell me if it's correct or not?

Answer 12

When you did
`(6x - 2x^2 + 3) - (4x - 3 - 3x^2)`
6x - 2x^2 + 3 - 4x + 3 + 3x^2
`6x - 4x - 2x^2 + 3x^2 + 3 + 3`
2x + x^2 + 6

Yes it is correct. I didn't realize that your post in the question box is the work. G☼☼d job !

Answer 13

I would write the answer in the power order though...

Answer 14

x²+2x+6, like this.

Answer 15

but you either way got this, because the order doesn't matter.

Answer 16

Thanks, @SolomonZelman !
