A company is engaged in the manufacture of wrist watches. If x watches are manufactured and sold, the cost is given by the expression 500+ 1.5x and the revenue is given by 4x. Find the profit from the sale of 1600 wrist watches.

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 *_*

I'm not sure you can get negative in holes, but in the case of -3+5=2the total is 2.
