Upon her grandmother's death, So-hyun received $100,000 to use for college expenses or for starting her family. The money is in a checking account for Sohyun to use as she chooses. How much tax does So-hyun own on the gift from her grandmother?

Since the money was in a checking account and no interest was accumulated on the 100,000 amount. So-hyun does not owe any tax to the government and will collect the whole $100,000 upon the death of her grand-mother.

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
