someone please help!!! ill give a medal to whoever answers this question. The product of (a − b)(a − b) is a perfect square trinomial. Sometimes Always Never
A perfect square trinomial is one whose factors are (a-b)^2 or (a+b)^2
a perfect square trinomial like I said before is \[(a+b)^2=a^2+2ab+b^2\]
so it is always or sometimes?
or \[(a-b)^2=a^2-2ab+b^2\] if you mutltiply (a-b)(a-b) an you get one of these two, then yea its always
