What is the definition for the "root of the equation" when doing algebra?

Thanks

"Root" is a more formal way to say "answer" or "solution".  A number is

called a root of an equation if when the number is substituted into the

equation and both sides simplified, the result is an identity, such as

2=2 or 8=8, etc.

Example:

There are two roots to this equation

x²+6=5x

They are 3 and 2.  3 is one root because when you substitute 3 for x

3²+6=5(3)

 9+6=15

  15=15

Also 2 is a root, because when you substitute 2 for x

2²+6=5(2)

 4+6=10

  10=10
