The answer must be written as a multiple of π. Give exact answers. Do not use decimal numbers. The answer must be an integer or a fraction. Note that π is already provided with the answer so you just have to find the appropriate multiple. E. g. if the answer is π2 you should enter 1/2. If there is more than one answer write them separated by commas.

what are the statements? and what do you mean by "216 2 1 6"?

c. side angle side. u shares the same sides

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!
