This symbol means that both sets could have the same elements. (a ⊆ b) true false

Hey!

Hope this helps...

What you want to know is this:

The symbol ⊆, which is known as a: subset

This means that (in this case): A is a subset of B, and set A is included in set B...

The answer is: false

Reason: All elements of set A are contained in set B, but not all elements of set B are contained in set A...

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!

130 degrees. i have no other way to explain
