Question

simplify: ((x-2)^-1-(-1)^-1)/(x-1)??

Answer 1

1/(x-2)

Answer 2

if i understood your expression correctly

Answer 3

how did you get to that? im not sure what to do with that fraction

Answer 4

hmm
(1/(x-2)+1)/(x-1)
=((x-1)/(x-2))/(x-1)
=1/(x-2)

Answer 5

how did you get that x-1/x-2?

Answer 6

hi do you wan to learn resolving this ?

Answer 7

sure!

Answer 8

ok let s go how do you begin it ?

Answer 9

do you know the property of exponentes ?

Answer 10

somewhat

Answer 11

write me please your exercise newly here

Answer 12

can you write it ?

Answer 13

um i can write it best i can like i did in the question? when i get to( (1/x-2) + 1)/(x-1) im not sure what to do after

Answer 14

Answer 18

this is sure like ?

Answer 19

ok so

Answer 20

there is (x-2) on the exponent -1 what sign this ?

Answer 21

this is equal ?

Answer 22

1/x-2

Answer 23

ok and (-1) on exponent -1 =?

Answer 24

1

Answer 25

no no

Answer 26

if x on exponent -1=

Answer 27

comen i wan to learn you it

Answer 28

ummm was it 1/-1?

Answer 29

yes right

Answer 30

ok now continue

Answer 31

there is -(-1) on exponent -1

Answer 32

ok 1/(x-2) -1 / (x-1)

Answer 33

no no

Answer 34

you have wrote -1 on exponent -1 = 1/-1 = ?

Answer 35

1/(x-2) +1 / (x-1)?

Answer 36

yes so when there are two fractions with denominators differents

Answer 37

so you need getting the denominator common

Answer 38

what will be in this case ?

Answer 39

Answer 47

multiply both fractions by that

Answer 48

by what ?

Answer 49

(x-2)(x-1). I am positive i got it now! thankyoou sooo much for helping me! I have to go

Answer 50

ok if you know what you need to do in continue all is right
