The first polynomial is completely factored; the numbers 121 and 36 don't have a common factor, and the variables are different, so you can't factor them either.
The other three can still be factored:
$(4x+4)(x+1)=4(x+1)(x+1)=4(x+1)^{2}$
$2x( x^{2} -4)=2x(x+2)(x-2)$
$3 x^{4} -15 n^{3} +12n^{2} =3 x^{4} -n^{2} (15n-12)$

The correct answer is the first one.

Use the graph below to answer the question that follows:

Answer:

D) Amplitude: 2; period: π; midline: y = 1

Step-by-step explanation:

The question is much more easily answered from the graph than from the description of the graph.

The amplitude is the extent of the peak above the midline (2), or half the peak-to-peak value (4/2=2). The midline is the line halfway between the peaks (1). The period is the horizontal distance between peaks of the same polarity (π).
