The price of Stock A at 9 A. M. was ​$15.69 Since​ then, the price has been increasing at the rate of ​$0.07 each hour. At noon the price of Stock B was ​$16.19 It begins to decrease at the rate of ​$0.13 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

understand that i don't know the answers

will someone answer his question

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!
