Hi, there are 2 systems of equations here and Ineed help in simplfying them
The first one is:
f1 = 3x^2 - 6y = 0
f2 = 3y^2 -6x = 0
I obtained
y = x^2/2 when plugging into y i got 3(x^2/2)^2 - 6x = 0
I then run into a problem.
The notes say the next step are
x(x^3-2^3). I do not understand where they got the 8 because when I solve it i got 12x^4 - 6x and I do not understand how that simplifys to x(x^3-2^3)
Someone please help.
thanks
