2. four candidates a, b, c and d are being voted for by 10 voters using preference schedules. the vote preference lists are: bcad, cdba, bcda, cdab, dabc cabd, cdab, bcad, abdc, bdac a) write out the preference schedule. c) who wins with instant runoff voting? b) who wins with plurality voting? e) who wins with borda count voting? d) who wins with pairwise comparison voting?

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.

answer: the answer is ann
