## BecomeMyFan=D 4 years ago another simple question

1. BecomeMyFan=D

$(1/(2-t)) + (1/(2+t)) = 2$

2. BecomeMyFan=D

i got to the point where 2 = 4/((2-t)(2+t))

3. BecomeMyFan=D

but i dont know how to go from here, and i dont even know if im right about this step

4. BecomeMyFan=D

i tried to simplify the denominator and got an answer 4/(4-t) am i correct?

I'm not so good at these either, re arranging things to get the right look. The best thing to do is to practice a lot of pre-algebra questions. Download some ebooks about that and it will show you how to do these easily. But don't spend months trying to find the best ebooks or videos on the internet. Just find a few and do them then suddenly you're on the right track. It's easy after that. And whatever you don't understand, you should immediately ask here like what you're doing right now. Good Luck :) And keep on persisting.

6. BecomeMyFan=D

ok, thx for the study tip

8. BecomeMyFan=D

SO, DOES anyone know if this is correct, what is the correct answer?

9. BecomeMyFan=D

i found t = 2 is this right?

No, this is not correct, when you simplify the denominator, you get4/(4-t^2)=2 , because t*t=t^2. Then multiply both sides by (4-t^2), this leaves you with 4=2(4-t^2) --> 8-2t^2=4 --> -2t^2=-4 --> 2t^2=4 t^2=2 --> $t=\pm\ \sqrt{2}$

mstud, nice explanation, you've been fanned
