Find ∬xz ds, where s is the triangle with vertices (1,0,0), (0,1,0), and (0,1,1).

Parameterize the triangle by the vector-valued function with




where and . Then the integral becomes

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 *_*
