Question
simplify: (9-x^-2)/3+x^-1)
if by this you mean
(9 - x^-2)/(3 + x^-1) and those are suppose to be negative exponents
(9 - (1/x^2))/(3 + (1/x))
((9x^2 - 1)/(x^2)) / ((3x + 1)/x)
((9x^2 - 1)/(x^2)) * (x/(3x + 1))
(x(9x^2 - 1))/((x^2)(3x + 1))
(x(3x - 1)(3x + 1))/((x^2)(3x + 1))
(3x - 1)/x
ANS : (3x - 1)/x or 3 - x^-1
