Question

Perform the indicated operation and simplify
(4c/c^2-1)-(2/c+1)

Answer 1

make denominators common

Answer 2

break up the c^2 - 1 into (c+1)(c-1) and then common denominator the thing.

Answer 3

Is the answer 2/c+1?

Answer 4

no.

Answer 5

it's 1/(c-1) isn't it?

Answer 6

no no sorry, 2/(c-1)

Answer 7

Thank you! Thats what I got.

Answer 8

factor:

[4c/(c-1)(c+1)]-[2/(c+1)]

multiply to get common denominator:

[4c/(c-1)(c+1)]-[2(c-1)/(c-1)(c+1)]

perform operation:

2c+2/(c-1)(c+1)

reduce:

1/(c-1)

alex was right i have failed you
