Two radicals that when multiplied together equal -20

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 *_*

(x) - (y) = (1 + 4i)

(3 + 6i) - (2 + 2i) = (1 + 4i)
