Try Example 2: You think you will be able to deposit GH€200, GH¢300, and GH¢400 at the end of each year for the next three years in an
investment that pays 6% interest. You currently have GH¢100 in the
investment. How much will you have in three years? In four years?

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.

126 maybe. sorry

its line 2 i just added the rest or else it wouldn't let me answer
