Pedro trabalha em um oficina mecânica junto com seu pai. ele recebe um salário fixo de r\$1800{,}00r$1800,00r, dollar sign, 1800, comma, 00 por mês, e dependendo dos consertos, ainda pode receber comissão.
ele guarda em média
9
1

start fraction, 1, divided by, 9, end fraction desse valor todos os meses em sua poupança.
depois de 1 ano, quanto ele terá guardado?

40 x 50 = 2000

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.
