C/d+2= f/g solve for c (show work)

C/d + 2 = f/g      (subtract 2 from each side)

c/d + 2 - 2 = f/g - 2

c/d = f/g - 2       (multiply d to each side)

c/d*d = d(f/g - 2)

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 *_*
