I think it’s asking to find the roots (zeros). Is so, then:
1.) There are two solutions, X = 1 plus or minus root 145/ 6.
2.) There are 2 solutions with components imaginary. X = 3/2 + i/2 and 3/2 - i/2
3.) There’s 2 solutions X = ( -7 plus or minus root 93)/2
4.) There is one solution X = -4
I hope that helps.
