Question

Need to find the LCD of this equation

Answer 1

Use 24(2x-1)(2x+1)

Answer 2

just use (2x-1)(2x+1)

Answer 3

24 is on another side.

Answer 4

I don't think it really matters, both should generate the same solution

Answer 5

i got 0=4x^2 - 1

Answer 6

um... no.

Answer 7

Yeah I don't think I did that right

Answer 8

I would use the 24 because it will get rid of the 24 on the other side.

Answer 9

I did use the 24

Answer 10

I got 48x-24-48x+24 which = 0

Answer 11

\[(1/(2x-1))-(1/(2x+1))=(1/24)\]
multiply by the LCD 24(2x-1)(2x+1)
\[24(2x+1)-24(2x-1)=(2x-1)(2x+1)\]
can you finish this?

Answer 12

0 = 4x^2 -1

Answer 13

\[48=4x^{2}-1\]

Answer 14

the 48's cancel.
24(2x) = 48
-24(2x) = -48
48 - 48 = 0

Answer 15

It'll look like 48x + 24 - 48x - 24 which = 0 on the left side. On the right it'll be
4x^2 -1

Answer 16

You forgot to distribute the -24 to -1 and get +24; 24+24 is 48. In the end, whatever x value you get should check out true when you plug it into the equation.

Answer 17

Once you solve for x;
x=7/2
x=-7/2

Answer 18

I honestly don't understand, but it's fine. I know quite well how to get the LCD and then solve equations with it, I just think the fractions threw me off on this problem. You were right by the way.
