How many terms in the polynomial 3x^2y^2+9xy+3x-y+10

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.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
