Astudent conducted a experiment on plant growth . plant a was fed a different fertilizer than plant b . before the experiment began, plant a measured 14 centimeters tall, and plant b measured 16 centimeters tall. at the end of the experiment, plant a measured 18.2 centimeters tall, and plant b measured 20 centimeters tall. which plant, a or b, grew at a greater rate ?

Plant A

Step-by-step explanation: Plant A underwent 4.2 centimeters of growth, whereas Plant B underwent 4 centimeters of growth. Plant A grew more drastically than Plant B

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!
