What value, in place of the question mark, makes the polynomial below a perfect square trinomial?x2 + 12x+ ?
Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.
there is no question mark
apos;s in the actual word, but the asker couldn't do the ; because the question mark is the only punctuation mark allowed in a question in this site. I'm sorry but I have the same question as the asker here, so I cant tell you what it means. But I improved the answer so the asker would know.
Use Pythagoras' theorem to calculate the hypotenuse of the square (or indeed any rectangle) you want to mark out. Then measure the sides from one corner and make sure the hypotenuse length is as calculated. You can mark the end points of the various sides with an arc and where they meet is where the square is.
