  1. x ² = 5

    x = ± √5


  2. factor out a 3 from the equation:

    3 (x^2-5) = 0

    that means that x^2 - 5 = 0

    so x^2 = 5

    x = +/- sqrt 5

    that is, x equals positive or negative square root of 5

  3. 3x^2 - 15 = 0

    3x^2 = 15

    x^2 = 5

    x = +/- sqrt 5

  4. 3x² - 15 = 0.

    So, 3x² = 15.

    => x² = 15/3.

    => x² = 5.

    x = ± √5. Hope that helped.....

  5. +/- sqrt(5)
