An abstract representation which symbolizes the concept of mathematical perfection. There are two main visual elements. The first is a standalone 'x' symbol, that is overlaid on a smoothly undulating gradient background, ranging from cool purples to warm oranges. The second is a perfect square which is drawn within a larger circle, representing the 'perfect square trinomial' portion of the question. There are numerical signs, like '+' and '11' scattered around the image but NOT forming any recognizable words or sentences.

What is the value of n so that the expression x^2+11x+n is a perfect square trinomial?

This is what I got and they were right ( Connections Academy )

C. 30.25
B. X = -1
D. No solution
B. 8 in

Hi is right. For connections academy it is C, B, D, B.

take 1/2 of the middle term coefficient and square that number

(1/2)(11 = 11/2
squared gives us 121/4

so x^2 + 11x + 121/4 = (x+11/2)^2

so n = 121/4 or 30.25 if you want a decimal
