Answer:
Therefore the roots of equation 1 are 1,3 1/2,-i,+i
Explanation:
in this question we have given
.......1
we have to find the roots of this equation
put x=1 in equation 1

It means x=1 is root of equation 1
now put x=3 in equation 1

therefore,x=3 is root of equation 1
Now put x=
in equation 1

It means x=
is also root of equation 1
therefore equation one can be written as

therefore remaining 2 roots can be calculated by solving

Therefore the roots of equation 1 are 1,3 1/2,-i,+i
