One way in which elements differ from each other is the structure of the electron cloud in each element’s atoms. in an electron cloud, an electron that is farther away from the nucleus has a greater charge than an electron near the nucleus. a smaller charge than an electron near the nucleus a higher energy than an electron near the nucleus. a lower energy than an electron near the nucleus.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
