Y^2-y=2 how do you solve?

     y² - y = 2
y² - y - 2 = 2 - 2
y² - y - 2 = 0
y = -(-1) +/- √((-1)² - 4(1)(-2))
                       2(1)
y = 1 +/- √(1 + 8)
                2
y = 1 +/- √(9)
            2
y = 1 +/- 3
           2
y = 1 + 3  or  y = 1 - 3
         2                  2
y = 4             y = -2
      2                   2
y = 2             y = -1

The Jewish beliefs that are based on the Ten Commandments are:

-The relationships in your life are incredibly important, especially those with God --- YOU SHALL LOVE GOD ABOVE ALL THINGS

-Do not take things that don’t belong to you --- YOU SHALL NOT STEAL

-Offer prayers to God, who is the only god you should worship --- YOU SHALL HAVE NO OTHER GODS BEFORE ME

The Ten Commandments are a set of ethical and worship principles, which play an important role in Judaism and Christianity. They include instructions such as worshiping God alone and keeping the Sabbath, as well as prohibitions against idolatry, murder, theft, dishonesty and adultery. Different religious groups follow different traditions in how to interpret and list them.

The Ten Commandments appear twice in the Hebrew Bible: in the books of Exodus and Deuteronomy. According to the story told in the book of Exodus, God wrote these commands on two tablets of stone, which he gave to Moses on Mount Sinai.
