I'm a further mathematics A level student, micromass. I appreciate your help but do you really think I would be attempting to to solve this equation if I was unaware that x^2=y works out as x=y^1/2? I know how graphical inequalities work pal, my problem is with the algebra, not the concept of an...
Homework Statement
Determine the possible values that y can take for the graph y=x+2/3-x^2
Homework Equations
N/A
The Attempt at a Solution
y=k
k(3-x^2)=x+2
3k-kx^2=x+2
-kx^2+3k-x-2=0
I've tried factorising my k terms and much more faffing about to no avail...help please? :s
Thanks awfully Mapes, but I was already aware that Uranium has 92 protons and 141-6 neutrons, significantly more than Iron. I may be sounding somewhat dim, I'm all too aware, but I was rather hoping there was more to it than that? Or am I just over-complicating this whole business?
