The number 1i is a root of the equation Find the other roots

The number (1+i) is a root of the equation. Find the other roots of the equation. Please enter your answer as numbers, separated by commas

Solution

One of the roots is x= 1 +i

By property of complex roots if one root is a+i*b thene there would be anothe root which is

the complex conjugate of a+i*b = a-i*b

So, other roots would be 1 - i
