Can you help me to solve the following inequation.

(x-2)/(x2 + x -2 )>=0

amistre64 · Answer

at first glance; the top should be greater than 2 and as long as the bottom factors and you eliminate the zeros ... it should be good

amistre64 · Answer

top greater than or equal to 2 ... missed a part ;)

amistre64 · Answer

it also appears to have a little bit near zero if the graph is right: http://www.wolframalpha.com/input/?i=%28x-2%29%2F%28x2+%2B+x+-2+%29

amistre64 · Answer

which probably accounts for the factoring

amistre64 · Answer

(x-2)            (x-2)
---------- = ----------
(x^2 +x -2)     (x+2)(x-1)

we have critical values of -2, 1, and 2 to test

<............-2.............1...........2............>
         -     va     +    va    +   (0)    + 
         -             -            +           +
         -             -            -            +
----------------------------------
         -             +            -            +
