Is this correct?

1. Find the solution set for x^2/(x+3) < 9/(x+3).

x^2/(x+3) < 9/(x+3)

x^2 < 9
x^2 - 9 < 0

(x-3)(x+3)<0

  • Precalculus -

    x ^ 2 / ( x + 3 ) < 9 /( x + 3 ) Multiply both sides with ( x + 3 )


    x ^ 2 < 9

    x < + OR - 3



    For :

    x = - 3

    x + 3 = 0

    and

    x ^ 2 / ( x + 3 ) = infinity




    For that reason solution is x < 3
