COMPLEX NUMBERS (factor x^2 - 3 over rationals, reals)

[Guest]

Factor x^2-3 over each set

a. the set of polynomials with rational coefficients
b. the set of polynomails with real coefficents

i don't understand this problem. how are you suppose to factor it if you dont know what the polynomails are??

how are you suppose to factor it if you dont know what the polynomails are??

Isn't the polynomial given as being "x² - 3"?

What method(s) are you supposed to use for this? Your subject line refers to complex numbers, but this polynomial has no complex zeroes...?

Please reply with clarification. Thank you.

\(\displaystyle 4^2 + 3^2 = c^2\)
