Answer:
rational
Step-by-step explanation:
Any number that can be written with a finite number of digits is rational. The given number is rational. (It has 5 digits.)
__
Any repeating decimal is rational.
If this were -9.2222..., it would be -9 2/9 = -83/9, also a rational number.
_____
A number is irrational if it cannot be represented exactly as a decimal or repeating decimal. That is, its decimal fraction part continues forever without repeating.
21 over 50 is
21/50.
The same thing, just put 21 on top, a line under it, and below that line, put the 50

Answer:
The Fundamental Theorem of Algebra assures that any polynomial f(x)=0 whose degree is n ≥1 has at least one Real or Imaginary root. So by the Theorem we have infinitely solutions, including imaginary roots ≠ 2i
Step-by-step explanation:
1) This claim is mistaken.
2) The Fundamental Theorem of Algebra assures that any polynomial f(x)=0 whose degree is n ≥1 has at least one Real or Imaginary root. So by the Theorem we have infinitely solutions, including imaginary roots ≠ 2i with real coefficients.

For example:
3) Every time a polynomial equation, like a quadratic equation which is an univariate polynomial one, has its discriminant following this rule:

We'll have <em>n </em>different complex roots, not necessarily 2i.
For example:
Taking 3 polynomial equations with real coefficients, with


2.2) For other Polynomial equations with real coefficients we can see other complex roots ≠ 2i. In this one we have also -2i
