You're welcome. But I am sure you are not crazy.
Ok ,I was going to ask to you to show the steps but suddenly I realized that I have got it...
Moving everything shouldn't change anything.
No the minus will not work in this case , as we are finding y^2 and y^2 cant be negative.
And the correct answer for x and y in my book and every where else is
Another thing I want to say,when I write the equation
to this,i.e.. moving the equation from one side to another
I get correct answer.Is here I am doing something wrong?
anonimnystefy yes what you got I also got that using that equation,but things changes when I use
The correct answer will be
And thanks for reply
Ok before you guys think too much let me tell you where I got this from...as I said its about square root fo a complex number
and its square root be c
--- Eq 2
Now every where they (in books,resource,etc) find x using quadratic formula, and after that they substitute x in Eq2 to find y.But what I am doing is I am trying to find y using quadratic formula ,but my signs(+/-) doesn’t matches. I think its math and what process we take it doesn’t matters ,the answer will be always same. I must be doing something very very silly...which is not coming into my mind right now but it will come later it always happens with me.
No you didnt got my problem ,I know that I am solving for y^2,and after solving for y^2 I have to remove the square,The problem is different just solve it and I will tell it about...
Hi all I am having problem with this qudratic equation with signs ,or I am doing something silly ,its all about square root of complex number.
We can write Eq 2 as
Now we can write Eq 1 as
Is my last equation correct? (I hope so),if yes please solve it using qudratic formula ,as far you can
I have did it but my answer is not matching with correct answer got from other process.The sign is not matching but yes if I write the last equation like this
,my answer matches.
