Question 549601
1/x+2/x^2 is less than or equal too 1/x-1
Assume the problem is:
{{{1/x}}} + {{{2/x^2}}} <= {{{1/((x-1))}}}
we can put the left side over a single denominator
{{{((x+2))/x^2}}} <= {{{1/((x-1))}}}
Cross multiply
(x+2)(x-1) <= x^2
FOIL
x^2 + x - 2 >= x^2
x^2 - x^2 + x - 2 <= 0
x - 2 <= 0
x <= +2, however x cannot = 1, (division by 0)
