Greg saved $8,000 prior to starting college. Each semester he must pay $2,5000 in tuition and fees. He knows he will eventually be in debt. What is the equation and how much debt Greg will be in if he graduates in 4 years (8 semesters) ?

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.

the anwser is d) 75°
