: I'm having problems........can anyone solve this equation?
: solve for x

: (1/x-2)+(3/x+3)= (4/x^2+x-6)

: Thanx a bunch!

:Step 1 - multiply through by x^2 and get
: x-2x^2+3x+3x^2 = 4+x^3-6x^2
:Step 2 - combine like terms and rearrange getting
: x^3-7x^2-4x+4
:Step 3 - factor and get
: (x+1)(x^2-8x+4)
:So you get x = -1, 4+2sqrt(3), 4-2sqrt(3)
