Tenemos un lío con el precio del boleto, la cantidad de personas que viajan y las 5 estaciones que visitaremos, en un principio. Somos 21 entre niños y maestra en 6º A y 6ºB. En 6ºC son 24 en total, incluyendo a la docente. Desde la Estación Central, de donde partiremos, nos cobran cada boleto $120 por persona. En cada estación nos cobran lo mismo. Nos hacen un 50% de descuento en el total, por ser un grupo numeroso. 1. ¿Cuántos viajeros somos en total? 2.-¿Cuánto pagaremos en una sola estación? 3- ¿Cuánto es el precio final, luego de las cinco estaciones?

step-by-step explanation:

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
