All rational numbers are whole numbers true or false

False.

Step-by-step explanation:

All rational numbers are not whole numbers because a rational number is a number that has a finite value that can be written exactly.

For example, a fraction like 3/5 is still rational because it is finite and can be written exactly.

False

Whole numbers are basically just natural numbers, just with 0, and not all rationals fit into that category, like decimals and fractions

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!
