Hmm, i am not sure, can u explain in brief how u got D, so that i can remember what i did in my School days !

kendricklamar2014 · Answer

Well the black big square is a negative, the two white squares are positive - black square, then a white square - three black squares

koikkara · Answer

Alright, so what does the last 3 black box means ?

kendricklamar2014 · Answer

-3

koikkara · Answer

Well, then i guessed is right, answer seems to be A ! >> rearranged from back to front... -3x+2 +2x^2-1^3 !

kendricklamar2014 · Answer

So is it A, or D?

I have never had similar or these type of questions. For this type of question I would definitely go with A.

koikkara · Answer

Hmm, seems like A, For example put a value x=1 and try to solve the equation after rearranging it as -3x+2 +2x^2-1^3 = -3(1)+2+2(1)^2-1 = -1 + 2 -1 = 0 ! Since this equation equates to Zero, the Polynomial is Stable with given model !

Note: Its just an assumption, may be right or wrong !
