Someone PLEASE help me !! 1. five times the product of two numbers x any y, divided by a third number z. what is the algebriac expression?

2. Seven times the product of two numbers x and y, less five, divided by thrice a third number z, what is the algebriac expression?

3. Half the product of two numbers x and y, minus five times a third number z. what is the algebriac expression?

4. three times a number x, minus four times a second number y, divided by seven times a third number. whats the algebriac expression?​

no lo entiendo lo que escribiste

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!
