How do i solve this equation -3.9÷1.3

- 3.9 / 1.3 = - 3/1 = - 3

Calculation Steps:

Conversion:

3.9 = 39/10

Unary Minus:

- 3.9 = - 39/10

Conversion:

1.3 = 13/10

Divide:

- 39/10 : 1.3

= - 39/10 * 10/13

= - 39 * 10/ 10 * 13

= - 390/130

= - 3

- 3

Hope that helps - 3

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.
