Question

1/x+8+16/x^2-64=1 Solve the equation, its a rational expression, show me how please? :)

Answer 1

(x^2-64)=(x-8)(x+8), so common denominator is: (x-8)(x+8)

Answer 2

((x-8)+16)/((x+8)(x-8))=1

Answer 3

Oh thank you, so now I solve it?

Answer 4

yea

Answer 5

Ok ill try, and you can check it for me :)

Answer 6

ok

Answer 7

0=-x^2-x-72 is what i got so far...

Answer 8

x-8+16=x^2-64
x+8=(x-8)(x+8)
1=x-8
x=9

Answer 9

How did you get second part? And thank you.

Answer 10

multiply both sides by (x-8)(x+8)

Answer 11

((x-8)+16)/((x+8)(x-8))=1
((x-8)+16)=(x+8)(x-8)
x+8=(x+8)(x-8)

Answer 12

divide both sides by x+8:
1=x-8
add 8 to both sides:
9=x

Answer 13

Isnt the answer -8,9?

Answer 14

i brought over -x-8 to the side with x^2-64 making it a trinomial, then I found those two answers.

Answer 15

why bring it over. my solutions is right

Answer 16

*my solution is right

Answer 17

i asked a math teacher, finally found one, and he said i was correct, but ill give you a medal for trying :)
