let $r$, $s$, and $t$ be the roots of the equation $x^3 - 2x 1 = 0$ in some order. what is the maximal value of $r^3 - s- t$?

boxplot

it would rotate about 180 degrees.

noncoplanar points are points that do not lie on the same line.

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
