## anonymous 5 years ago find 2 solutions..

1. anonymous

$y ^{2}-19y ^{-1}+88=0$

2. anonymous

$y-19^{2}\over2$ is what I have, as well as -9 over 4.. But idk if this is correct. ?

3. anonymous

are you sure the question is right?

4. anonymous

yeah. it says to find the 2 solutions for that equation.

5. anonymous

Because i am getting very complicated answers

6. anonymous

it could be one answer, I would just gave to enter the same answer twice. what are you getting?

7. anonymous

it got imaginary number and everything

8. anonymous

have you covered imaginary numbers yet?

9. anonymous

yeah a bit. It could be the answer.

10. anonymous

are you familiar with wolfram alpha?

11. anonymous

yeah I'm on it. I actually was trying to put this problem in by it wont let me do the -1 power.. Do you know how to type it in? ^-1 didn't work

12. anonymous

Hold on let me send you link

13. anonymous

k thanks

14. anonymous
15. anonymous

it came up as -19 over y... that might be why it's wrong.. it needs to be to the -1 power

16. anonymous

y^-1= 1/y

17. anonymous

ohh. :) i didn't know that.

If you have negative exponent, you can send it so the denominator as a positive exponent

19. anonymous

nagative exponent in numertor can be written as postive in denominator
