you have to distinguish between factorization and solving of the equation.
To solve the equation you have x1 and x2 as you mentioned, this gives you the roots of your equation only. But, the factorization of the the quadratic function is given by
Hi,
I have a simple question regarding solving a quadratic function
I tried to solve it as follows in general for y=y1 find the roots of the quadratic equation:
Hence, in more detail...
for :
assuming
However, this is not producing the desired result. For example, assume the following function
and following the solution above gives:
and
None of them being 3 as I would expect. Can someone point me in the right direction or a link with info I can look up?
Thank you in advance.

I believe Excel follows the standard order of operations. You'll always need parentheses in situations like that when you're entering an expression in plain text. The horizontal line in a fraction (called a vinculum) acts as a grouping symbol in handwritten expressions, but we don't have that luxury when we just use a / for division.
