Question 1129
<pre><font face = "courier new">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
