\[x^2-7 \over x^2-x-6\]<1
OpenStudy (smurfy14):
i got to that part so what would the answer be after i make a sign chart?
OpenStudy (mertsj):
If you have to make a sign chart, then you need to have the right side = 0 so subtract 1 from both sides.
OpenStudy (smurfy14):
what would that look like?
OpenStudy (mertsj):
x^2-7/(x^2-x-6) -1<0

Now write a common denominator
OpenStudy (mertsj):
(x^2-7)/(x^2-x-6)-(x^2-x-6)/(x^2-x-6)<0
(x^2-7-x^2+x+6)/(x^2-x-6)<0
(x-1)/(x-3)(x+2)<0
OpenStudy (mertsj):
Now make your sign chart
OpenStudy (mertsj):
_______|_____________|_____________|_________
-2 1 3
(x-1) - - + +
(x-3) - - - +
(x+2) - + - +
Fraction - + + +
So we see that the solution is x <-2
