SOLUTION: I do not know what to do next, I have worked as far as I can but I do not now what to do know. 2x^2-18/4x^8 Divided by 6x^2+6x-36/8x^4 Here is what I have done 2x^2-18/4x^8 X

Question 137478: I do not know what to do next, I have worked as far as I can but I do not now what to do know.
2x^2-18/4x^8 Divided by 6x^2+6x-36/8x^4
Here is what I have done
2x^2-18/4x^8 X 8x^4/6x^2 + 6x -36
2(x^2 - 9)/4x^8 X 8x^4/6(x^2 + x - 6)
2(x^2 - 9)/4x^8 X 8x^4/6(x^3 -6)
x^2 - 9/2x^8 X 4x^4/3(x^3 - 6)

Here is what I have done
2x^2-18/4x^8 X 8x^4/6x^2 + 6x -36 (good)
2(x^2 - 9)/4x^8 X 8x^4/6(x^2 + x - 6)(good)
2(x^2 - 9)/4x^8 X 8x^4/6(x^3 -6)(wrong here because x^2+x is not x^3)
2(x^2 - 9)/4x^8 X 8x^4/6(x^2 + x - 6)=
16(x^2 - 9)x^4/24x^8(x^2 + x - 6)=
2(x^2 - 9)x^4/3x^8(x^2 + x - 6)=
2(x^2 - 9)/3x^4(x^2 + x - 6)=
2(x-3)(x+3)/3x^4(x+3)(x-2)=
2(x-3)/3x^4(x-2)
