What is 3x-8=8x+4/2 solve for variable

First you need to get your variable by itself

3x - 8 = 8x + 4/2

subtract 3x from 8x

-8 = 5x +4/2

subtract 4/2 from -8

-10 = 5x

divide by 5

x = -2 

)because it's going in order of the math sign

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 *_*
