Suppose b(t) is the length of a bamboo shoot, measured in kilometers, at time t, measured in days. then b′(t) represents the rate at which the length is changing at time t, and b′′(t) is the rate at which the rate of change is changing at time t.

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 *_*
