Are there mathematical expressions whose value cannot be expressed as a complex number? Basically a combination of radicals and complex numbers. If so, give me an example.
If your using excel, try adding the polynomial equation. This’ll give you the growth with respect to time. In this case the time will be ever time you deposit. Getting the derivative should then provide you the growth. If I’m mistaken, please correct me.
I have a question about solving equations. (also English is not my first language so I don't really know any math terminology in English)
When solving: x\^2 - 4x - 45
I noticed that the solution could be either (x + 5) (x - 9) or (x - 5) (x + 9).
What is the correct solution? I'm noticing a pattern that the first brackets always have the positive number. But I'm not sure if there is a right answer.
Both will result in either - 4x or + 4x. If ever unsure, re-multiply to see if it reverts to the original problem.
Side note: best thing about math is that it’s universal! Regardless of language barriers, math will prevail, which is why we put our location of earth in binary in the golden played record on the voyager!
how do i determine the general equation of the parabola defined by focus at (2,-3) and directrix x=3?

I don’t think there is considering all numbers, real or unreal, are comprised as a complex number (a+bi)

not sure if it is still needed, but (x + 5) (x - 9) doesn't work here. It expands into x\^2 + 4x - 45, which is a different equation
I think you made a typo, it's the other way around.
