if a polynomial equation of degree n has exactly one distinct real root, what can you conclude about the value of n?
someone pls help
>>8737764
it's a non-negative integer
>>8737768
why,
explain the reasoning pls
>>8737773
its non-negative because it has a root
>>8737773
you just got it to feel it bro
In all seriousness, write out a couple of simple quadratic examples and see for yourself.
>>8737774
-1 has a root (i)
>>8737796
-1 is a constant polynomial, it doesn't have any roots
n is odd. If n was even, there would be at least two real roots as imaginary roots exist in complex pairs

He said real root. What we know is that either there is two roots or one root of multiplicity two i think.
>>8737818
multiplicity does not need to be 2
see: x^4 = 0
>>8737810
wrong
(x-1)(x-i) has one distinct real root
>>8737810
>(x-1)(x-i)
only if the coefficients are all real.
>>8737764
(x-a)^n will always have one distinct root (x=a) for positive values of n. Technically n doesn't even have to be an integer, though by definition polynomials have nonnegative integer exponents. So you can't conclude anything that wasn't already given by "a polynomial equation".

What about 0, it's constant polynomial too, but it has infinitely many roots
>>8737764
N is odd, polynomials have real coefficients and integer exponents.
>>8738795
it doesn't have a distinct real root so it's not relevant to the question

>N is odd, polynomials have real coefficients and integer exponents.
???
polynomials can have coefficients in any ring, you certainly can't say (x-i) isn't a polynomial
>>8739030
>polynomials have real coefficients
