(6)/(X^-4) + (5)/(X^-2)

- Algebra 2 -
**Reiny**, Monday, February 2, 2009 at 8:44amthe common denominator would be

(x^2-4(x^2-2), so

(6)/(X^-4) + (5)/(X^-2)

= [6(x^2-2) + 5(x^2-4)]/[(x^2-4(x^2-2)]

= (11x^2 - 32)/[(x^2-4(x^2-2)]

(are you sure the second denominator wasn't (x-2) ?

it would have worked much better)
