5/8 of the 64 musicians are guitarists. some of the guitarists play jazz solos, and the rest play classical solos. the ratio of the number of the guitarists playing jazz solos to the total number of guitarists in the contest is 1: 4. how many guitarists play classical solos in the contest?

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.
