Okay, this one is a bit tricky. Luckily, there's a trick!
We want it to be of the form Ax^2+Bx+C=0. So, try letting x^2=y^(-1). Then x=y^(-1/2). We are lucky in that this works perfectly- then we get x^2-8x+12=0.
Now solve for x by factoring to get x=2,6.
Now, make sure to remember we want y, not x, so if x=y^(-1/2), y=(y(-1/2))^(-2)=x^(-2), so y=1/4 and 1/36.
You can test these values in the original equation and see they work.
