If the ratio of the corresponding sides of similar polygons (or the
radii of similar circles) is m:n,
then the ratio of their areas is
m
2
:n
2
. If the radius of a sphere is
multiplied by a factor of 4 to
create a larger sphere, what is the
ratio of the surface areas of the
two spheres?

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 *_*
