Mark DeRosa, a Major League Baseball player, was a second baseman for the Chicago Cubs in 2007. Consider the experiment of DeRosa making a batting appearance. There are five experimental outcomes: He is out, he advances to first base, he hits a double, he hits a triple, or he hits a home run. Define the random variable x as the number of bases that DeRosa advances on the baseball diamond from his batting appearance. Thus, the values of x are:

the answer is c)8

step-by-step explanaction:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
