Afirst number plus twice a second number is 20. twice the first number plus the second number totals 22.

I just did it by trial and error but I got that the one number is 6 and the other 8.

2*8 + 6 = 16+6 = 22

2*6 + 8 = 12+8 = 20

What is your question?

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 *_*
