Degree 3 polynomial with integer coefficients with zeros -2i and 7/5

Step-by-step explanation:

Polynomial Construction

A polynomial can be constructed by knowing its roots or zeros and the leading coefficient.

In our example, we have only two roots and no leading coefficient, thus the solution provided will be only one of the infinite possible solutions.

There is one imaginary solution x=-2i, we know it the polynomial has integer coefficients, then the imaginary roots come in conjugated pairs, meaning the other root must be x=+2i. Having completed all the roots, our polynomial is

Operating

We can discard the denominator since the roots of the polynomial will be the same with or without it, and we need the coefficients to be integer.

Rearranging

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
