Maria is putting up a shelf on a wall in her closet. The figure below shows △ABC , which represents a bracket that will be used to support the shelf. image fb1743f8e9494c6a86b28701192bbf87 Determine AB , the length of the part of the bracket that is attached to the wall, and m∠ ABC , the measure of the angle that the bracket makes with the wall. Use the dropdowns to make each statement true. The length of AB¯¯¯¯¯ A B ¯ is approximately

move it to the other side

step-by-step explanation:

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!
