Interest earned by an investment is given by I = Prt, where is the amount of
interest earned, p is the principal
amount, r is the interest rate, and t is the
amount of time in years. How much
interest will a $2,000.00 investment earn
in 3 years with an interest rate of 87?

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.
