    Answer:

    x=\frac{1}{3}    or    x = -\frac{1}{3}

    Step-by-step explanation:

    9x^{2} -1 = 0

    9x^{2}  = 1

    x^{2}  = \frac{1}{9}

    x  = +-\sqrt{ \frac{1}{9}

    x=\frac{1}{3}    or    x = -\frac{1}{3}

    Answer:

    x=1/3

    Step-by-step explanation:

    9x^2-1=0

    Add 1 to both sides

    9x^2=1

    Divide both sides by 9

    x^2=1/9

    Square root both sides

    x=1/3
