Select the expression that represents the following statement: 52 minus 4 times the difference of 13 and 7. answers 4 x (13 + 7) − 52 4 − (7 − 13) + 52 52 − 4 x (13 − 7) 52 − 4 + (13 − 7)

52 -4 X (13-7)

Step-by-step explanation:

Remember BODMAS.

We do brackets, then we do multiplications and divisions , then we do addition and subtractions.

As we want first the difference of 13 and 7, we must put them in brackets.

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.
