Which complex number will be plotted below the real axis and to the right of the imaginary axis?

Answer: The correct answer is (B)
Step-by-step explanation: We are given to select the correct complex number that will be plotted below the real axis and to the right of the imaginary axis.
We know that a complex number can be treated as a point in XY-coordinate plane as X-axis is the real axis and Y-axis as the imaginary axis.
That is, x + iy = (x, y).
Therefore, the given points and the corresponding quadrants can be written as
2i - 5 = (-5, 2) Quadrant II
4 - i = (4, -1) Quadrant IV
5 + i = (5, 1) Quadrant I
-5i = (0, -5) Y-axis
-2 - i = (-2, -1) Quadrant III.
Now, the quadrant that lies below the X (real) axis and to the right of Y (imaginary) axis is Quadrant IV.
So, the correct complex number that will be plotted below the real axis and to the right of the imaginary axis is
Option (B) is CORRECT.

The fundamental theorem of algebra states that a polynomial with degree n has at most n solutions. The "at most" depends on the fact that the solutions might not all be real number.
In fact, if you use complex number, then a polynomial with degree n has exactly n roots.
So, in particular, a third-degree polynomial can have at most 3 roots.
In fact, in general, if the polynomial has solutions
, then you can factor it as
So, a third-degree polynomial can't have 4 (or more) solutions, because otherwise you could write it as
But this is a fourth-degree polynomial.
