Question

need to solve rational expression
1+1/x-1=30/x^2+1
Can you help solve this equation

Answer 1

cross multiply. it is a cubic equation

Answer 2

x/x-1= 30/x^2+1
x^3+x= 30x - 30
x^3 -29x +30=0

Answer 3

Is the equation stated correctly? Is it really:
\[1+1/(x-1)=30/(x ^{2}+1)\]
If so it appears the first 1 was ignored in the solution unless 1+1/(x-1) is the same as x/(x-1). It isn't

Answer 4

I can see I was wrong about that! Never mind it is the same.
