I multiplied the entire function by x and x-4 and after doing that I got down to the quadratic equation
I did the quadratic and got
x=1.525 and -8.525
I feel like I made a mistake because when I plug in both of those answers for x separately, it never works out. Not sure if I made an error in calculating or in plugging in, or if there is no solution.
your answer is wrong.... redo the problem and move 1.5 and make it 5.125
I'm not quite sure what you mean. Can you please elaborate
Not sure you should go by me, because I took it down wrong the first time, but I got:
x + 11/x - 4 + 7/x^2 + 4x = 0
Gathering and multiplying by x^2:
5x^3 - 4x^2 + 11x + 7 = 0
Does this makes sense to you in the context of your course?
