The sum of the complex roots of the equation x^4-2x^3+x-380=0 is

Question

Accepted Answer

Correct answer: D. (d) x^4-2x^3+x-380=0 Put x=5 5^4-2. (5 )^3+5-380 ⇒0=0 So, x=5 one real root Put n=-4 (-4 )^4-2 (-4 )^3+ (-4 )-380=0 ⇒0=0 So, n=-4 is second real roots. Let and are two other roots... ∴ + +5-4=- (-2 )1 ⇒ + =1

$The sum of the complex roots of the equation x^{4} - 2 x^{3} + x - 380 = 0 is$
