Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*

There should only be 1 solution

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )
