Use the given functions to answer the qu f(x) = 4x2 – 3x + 8 8(x) = -6x2 - 1 Which expression represents f(x) + g(x)? O A. -2x2 – 3x + 7 O B. –2x2 + 3x + 9 O C. 2x2 – 3x + 7 O D. 2x2 – 3x + 9​

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.
