What are two numbers i can use to multiply to 4, but also i can add those numbers to equal 2? any integers are okay.

No 'real' numbers can do that job.
The two numbers are complex.

They are ...

       1 + i √3
and
       1 - i √3 .

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 *_*
