5x² - 6 = 0

Add 6 to both sides

    5x² = 6

Divide both sides by 5

     x² = 6%2F5

      x = %22%22+%2B-+sqrt%286%2F5%29

Rationalize the denominator by multiplying inside the
radical by 5%2F5 to make the denominator become a square:

      x = %22%22+%2B-+sqrt%28expr%286%2F5%29%2Aexpr%285%2F5%29%29

      x = %22%22+%2B-+sqrt%2830%2F25%29

      x = %22%22+%2B-+sqrt%2830%29%2F5
