Okay, something is off here for me
What I did is this
X ^ 2 = xy
I took the square root of x ^ 2 so I ended up with
x = square root of (x.y)
which means x = square root of (x) * square root of (y)
Therefore, square root of (y) will equal x/square root of (x)
If x is = 0 then it will be undefined. You can't divide by 0.
The same applies to the value of square root of (x) which will equal x/square root of (y). Therefore, y can't equal 0.
Anyone help me here?
First of all, square root of x^2
is |x|, not x. Do not take the square root until and unless you really need to.x^2 = xy
You do not divide both sides by x here. You lose out on a solution.
What you can very safely do is x^2 - xy = 0x(x-y) = 0
Now, either x = 0 or x = y or both
Since x and y are different, x must be 0.
When x = 0, no matter what the value of y, x^2
is equal to xy since both sides are equal to 0.
Since x = 0, you cannot re-write this as y = x^2/x
