Observa el trapecio isoceles PQRS en el plano cartesano. La ilustracion esta demostrada ya pero no tiene contestacion.
Necesito saber:
A. Cuantas uniddes mide el lado QR?
B. Cual es la distancia entre los puntos Py R.

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

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!
