Question

Please explain...

Answer 1

its simply, really

Answer 2

\[6\div r ^{2}-1 -1\div2=1\div r-1\]

Answer 3

lcd=\[(r ^{2}-1)(r+1)(2)?\]

Answer 4

the last term is suppose to be 1/r+1

Answer 5

is this your question?:\[\frac{6}{r^2-1}-\frac{1}{2}=\frac{1}{r+1}\]

Answer 6

yes

Answer 7

use the fact that:\[r^2-1=(r+1)(r-1)\]

Answer 8

okay r^2-1 = (r+1)(r-1) make all the denominators match

Answer 9

and then multiply both sides by (r+1). that should simplify the expression.

Answer 10

I need to leave now - but hopefully there are plenty of people here that can assist you...
