solve it :)

Answer 2

-2x+14x-6x=-1?

Answer 3

-2x^2+14x-6x=-1

Answer 4

how did you come up with an exponent?

Answer 5

cause you multiplied (-x)*((2x)

Answer 6

oh okay i see now.

Answer 7

when you multiply same variables you add their exponents

Answer 8

oh okay. Do I add like terms?

Answer 9

yup

Answer 10

so would i end up with: 6^2=-1?

Answer 11

where did you get that ?

Answer 12

i add the -2x^2 and 14x then subtracted 6.

Answer 13

You can't add -2x^2 and 14x they have different variables

Answer 14

okay then i would do 14x-6x=8x: 2x^2+8x=-1?

Answer 15

im confused now...

Answer 16

-2x^2+8x=-1
you are almost right you forgot the negative sign

Answer 17

-2x^2+8x=-1

Answer 18

typo. sorry

Answer 19

i dont know what that means.. yet.

Answer 20

transfer -1 to the right side of the equation :)

Answer 21

how would i do that if there are both variables on the right and -1 isnt a variable?

Answer 22

it is like adding both sides of the equation by +1 . so that you will cancel out -1 on the right side

Answer 23

where would I add it since there both variables? could you show me an example?

Answer 24

2x+1=2
2x+1-2=2-2
2x-1=0
