What of the following is the complete factorization of the polynomial - x^3+2x^2+x+2 A.(x+2)(x+i)(x-i)
B. (x-2)(x+i)(x-i)
C. (x-2)(x+i)(x+i)
D. (x+2)(x+i)(x+i)

9514 1404 393

  A. (x +2)(x +i)(x -i)

Step-by-step explanation:

The complex factors must be conjugates, eliminating choices C and D.

The product of the complex factors will be (x^2 +1) so the remaining factor must have a constant of +2 in order for the constant in the product to be 2.

  p(x) = (x +2)(x² +1) = (x +2)(x +i)(x -i)

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

step-by-step explanation:

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
