a) 16  =

b) 1   =

c)

d) 3 =

e)  2  =

Step-by-step explanation:

16.666666 = 16  = (16 * 3) + 2 =

1.6666666 = 1 = (1 * 3) + 2 =

.333333 =

3.55555 = 3 = (3 * 9) + 5 =

2.111111 = 2 = (2 * 9) + 1 =

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.
