You can put this solution on YOUR website! please explain.
b^2-2bc+c^2=(b-c)^2
----------------------
I'll show you that the right side of the equation is the
same as the left side:
--------------
(b-c)^2
=(b-c)(b-c)
= b(b-c)-c(b-c)
=b^2-bc-bc+c^2
=b^2-2bc+c^2
==============

You can put this solution on YOUR website! => these are the square of binomials: and
Important to know:
If the binomial has a minus sign, then the minus sign appears     of the trinomial.
If the binomial is , then the middle term will be ,
and if the binomial is , then the middle term will be ;
therefore, we can use the  (" "),
to state the rule as follows:
The square of  produces the following three terms:
1. The square of the first term of the binomial:
2. Twice the product of the two terms:
3. The square of the second term:
The square of  , called a perfect square trinomial,
has that form: .
So, if your square your binomial , it will be:
is the square of .
is twice the product of .
is the square of .
