Find all solutions of the following equation. (If there are more answer boxes than answers, enter NONE in the extra boxes.) a3x3 + 1000 = 0
x = 1
(real solution)
x = 2
(smaller imaginary part)
x = 3
(larger
I was able to figure out part one and for 2 and 3 this is what i came up with but they are incorrect.
ditto to what Constantine said
i assume by a3x3 you mean ??
in that case, note that what you have is:
you can use the sum of two cubes formula:
the first factor gave you the first solution. use the quadratic formula on the second factor to get the second solution. here your and your
