Typing with capital letters and exclamation points is an email is an example of

Probably poor etiquette.

Explanation:

If you give me answer choices I may be able to help even more. But as far as I know typing with all caps and exclamation points in an email is not the proper thing to do.

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.

hope this
