1. La ecuación x3-2x2-5x+6=0 tiene tres raíces enteras, utiliza la regla de Ruffini para calcularlas:
x1=
x2=
x3=

2. Efectúa la división: (4x3-8x2-9x+7) : (x-3)

3. Calcula el valor de m para que el polinomio x4+x3+mx+2 sea divisible por x+2

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
