    Solving Inequalities

    I have what seems to be a basic question in front of me but even when using the quadratic equation I get some rather impossible numbers.

    x^2 - 4 < 1 (a fraction...not sure how to transcribe that one)
    x + 2

    Can anyone show me how to solve this?

    x^2 -4 < x+2 multiplying up

    then take it over:

    x^2 - x -6 <0

    using quadratic:
    x=-1 (+/-) (rt(1-(4*-6))/2)

    x= -1 (+/-) 5 all divided by 2

    x=-3 and x= 2

    then you do the rest.

    someone might show you better with latex.
