Hello,

It's been about 6 years since I've had to do Algebra and I've come
across the following problem:

x4 - 4x² + 3 = 0

(x4 is x to the 4th, not x times 4). I'm not sure what is supposed to
happen to the first x in the equation when you divide the x² and
everything else by 4.

Here's an image of what I'm talking about, in case the above doesn't
make any sense:

The last line there is wrong. It should be

x^4/4 - x^2 = -3/4.
