The act of transforming (or manipulating) data is permissible because the same rule is applied to all data in a given set. In other words, you're not just transforming some of your data while leaving other data points alone. The same concept appears in algebra when isolating a variable to solve a given equation. As long as each step applies the same rule to both sides of the equation, it is permissible. Even driving safely by car is possible because all drivers agree to drive on the same side of the road. Can you think of two other examples where a similar logic might apply?

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!
