(-2)^1/2 is a complex number.
Square of 2 and - 2 is 4 .... so there isnt really a square root of -2 or any other -ve no .... a calci will show it as E (infinity
)
So we write it as 2i where i=(-1)^1/2
So acutally 2i+3 means (-2)^1/2+3
Thats a complex / imaginary number.
Was that a question or did i say that somewhere ?
I dont think i did
So that must be a question

Cookie is right. I just started studying this equation with 2 answers.
any problem that is like
ax^2 + bx + c = 0
you can find two answers for. There is more then one equation to do so. But the one Cookie posted is a better one for this equation.
WTF ... both of us said the same thing ... mine had a typo which was corrected
He said it in detail ... i just multiplied and showed it cause i was in a hurry ... i didnt show the answer as it wasnt a perfect whole number
I told all this on msn
