    Answer:

    ±2 sqrt(3) =x

    Step-by-step explanation:

    12 – x^2 = 0

    Add x^2 to each side

    12 – x^2 + x^2 = x^2

    12 = x^2

    Take the square root of each side

    ±sqrt(12) = sqrt(x^2)

    ±sqrt(4*3) = sqrt(x^2)

    ±sqrt(4) sqrt(3) = x

    ±2 sqrt(3) =x

  1. Answer:

    x = -2sqrt(3), 2sqrt(3)

    Step-by-step explanation:

    12 – x² = 0

    x² = 12

    x = +/- sqrt(12)

    x = +/- 2sqrt(3)

    sqrt: square root
