La ganancia de una empresa se representa mediante la expresión: g= 20v2 - 40v - 60, donde "g" representa la ganancia (en miles de pesos) y "v" la cantidad en millares de productos vendidos. ¿cuántos productos se deben vender como mínimo para que la empresa obtenga ganancias?

The profit of a company is represented by the expression: g = 20v^2 - 40v - 60, where "g" represents the profit (in thousands of pesos) and "v" the amount in thousands of products sold. How many products must be sold at least for the company to make a profit?

The curve g(v) = 20v^2 - 40v - 60 represents "profit."  Set this = to zero and solve for the values of v at which g(v) is zero.  Answers:  v=3 and v=-1.  The profit function will be + for values of v greater than 3 (answer).

La curva g (v) = 20v ^ 2 - 40v - 60 representa "ganancia". Establezca this = en cero y resuelva los valores de v en donde g(v) es cero. Respuestas: v = 3 y v = -1. La función de ganancia será + para valores de v mayores que 3 (respuesta).

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 *_*
