Is this trinomial a perfect square
if the trinomial starts with x^2 and 1/2 of the middle term coefficient squared equals the last term, then it is a perfect square.
tell me what you found.
i thought it was not a perfect square. because i tried factoring it but it won't come out.am i wrong then
but in the original is x^2-6x+9
(x+3)^2 is incorrect. It is (x-3)^2:
and there is your answer.
Do you get it?
therefore it is a perfect square is this correct then
sorry emily, of course I meant (x-3)^2, it was a typo. sorry, its getting late where I am.
Yes it is. Good job!
