Factor the expression completely over the complex numbers. x^4 − 625 enter your answer in the box.

You have to observe that and 625 are both squares (of and 25, respectively). So, you can use the "difference of square" pattern for factorization:

to write

Note that, again, is a difference of square:

On the other hands, admits no factorization, because it's a second-degree polynomial (thus a parabola) with no solutions.

So, the whole expression becomes

(x-5)(x+5)(x-5i)(x+5i)

Step-by-step explanation:

I took the quiz.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

answer: (1,3) (3,-1) (5,-5) ?
