Answer:
i√17 ≈ 4.123106i
Step-by-step explanation:
The square root of a negative number is "i" times the square root of its absolute value. It is an imaginary number.
_____
i is generally the symbol used for √(-1). In some fields, such as electrical engineering, where i has a different meaning, the symbol j may be used instead.
For this case we must write in algebraic symbology the expression described above:
We have an equation, then:
- x squared plus y squared:

- minus 2x plus 7y plus 1:

- equals zero:

We construct the equation:

Answer:

A since they didn’t tell you what the other students have gotten therefore you can’t complete the data
x^2b + t = x^2e
x^2e - x^2b = t
x^2(e - b) = t
x^2 = t /(e -b)
x = √[t /(e -b)] or x = - √[t /(e -b)]
Using the Factor Theorem, the polynomial is given by: 
- The graph is sketched at the end of the answer.
The <em>Factor Theorem</em> states that a polynomial function with roots
is given by:
In which a is the leading coefficient.
In this problem, the roots are:
- Root of -4 with multiplicity 4, hence
.
- Root of -1 with multiplicity 3, hence
.
- Root of 5 with multiplicity 6, hence

Then:


- Positive leading coefficient, hence
.
- 13th degree, so it is odd.
Then:

At the end of the answer, an sketch of the graph is given.
