Question 994716: I have a question my teacher talks about distributive property today and this is what I learn.
(X+2)(X+2) is equal to x^2+4x+4 not x^2+4
I don't understand when to do the distributive property and when to do the actual multiplication with the expression.

(X+2)(X+2) is equal to x^2+4x+4 not x^2+4
---------
(x+2)*(x+2) = x*(x+2) + 2*(x+2)
= x^2+2x + 2x+4
= x^2 + 4x + 4
--------------
I'm convinced.

The Distributive Property is an algebra property which is used to multiply a single term and two or more terms inside a set of parentheses. Take a look at the problem below.
+2%283+%2B+6%29
Because the binomial "3+%2B+6" is in a set of parentheses, when following the Order of Operations, you must first find the answer of 3+%2B+6, then multiply it by 2. This gives an answer of 18.
so, in your case we have two binomials to multiply:
%28X%2B2%29%28X%2B2%29=X%28X%2B2%29%2B2%28X%2B2%29...here you use The Distributive Property
%28X%2B2%29%28X%2B2%29=X%2AX%2B2X%2B2X%2B2%2A2
%28X%2B2%29%28X%2B2%29=X%5E2%2B4X%2B4
