Question

with the restriction x does not = 2 what is the simplified form of (2x-7/x-2) - (x-5/x-2)

Answer 1

\[\frac{a}{b}-\frac{c}{b}=\frac{a-c}{b}\] make sure to use parentheses, so the first step is to write
\[\frac{2x-7-(x-5)}{x-2}\] then you can clean up the numerator by removing parentheses and combining like terms

Answer 2

i did that and it gave me x-2/x-2 which is one but that is incorrect

Answer 3

for your problem you get =1 (x≠2)

Answer 4

i got 1 for the simplified answer, but its incorrect, and I don't know why. 2x−7−(x−5) = x - 2 is what i got and x-2/x-2=1

Answer 5

what makes you think 1 is wrong ? (strictly speaking the answer is 1 for x≠2)

are you sure you typed in the correct question ?

Answer 6

yes, im sure. I submitted one already, and it was incorrect...

Answer 7

hmm i am going to stick with that answer

Answer 8

(2x-7/x-2) - (x-5/x-2)

I assume this is a sloppy version of
(2x-7)/(x-2) - (x-5)/(x-2) = 1 for x≠2

however, if we interpret using order of operations
2x - 7/x -2 - (x -5/x -2)
which is different.

If you are sure the question is
(2x-7)/(x-2) - (x-5)/(x-2)
then ask your teacher, because the answer is 1, x≠2

Answer 9

this
\[\frac{2x-7}{x-2}-\frac{x-5}{x-2}\] is the correct question right?

Answer 10

it could be an error in the program, ill try it again though...and yes those are the right questions.

Answer 11

ok

Answer 12

hmm...idk, ill ask my teacher. thanks for the help though!

Answer 13

she says that's correct! thank you both so much!
