Question

solve

Answer 1

yes?

Answer 2

(6/y+5)-(9/y-5)=(15/y^2-25)

a.-30 b.90 c.64 d.30

Answer 3

i keep getting 45.923

Answer 4

let me try it out first

Answer 5

Is this the problem?

\(\dfrac{6}{y+5}- \dfrac{9}{y-5}= \dfrac{15}{y^2-25}\)

Answer 6

yes

Answer 7

Start by factoring the last denominator.
What do you get?

Answer 8

-4*6*sqrt(6)*a

Answer 9

What? I don't see an "a" anywhere in the problem. Where did you get "a" from?
Just factor \(y^2 - 25\)
It's the difference ff two squares.

Answer 10

Use this to factor the third denominator.
\(a^2 - b^2 = (a + b)(a - b)\)

Answer 11

Sorry, gtg. It's late.
