Question 140692: ok i do not understand how to do this......X/X+2+ 3/X-2=7/X

X/X+2+ 3/X-2=7/X
----------
Multiply thru by the least common multiple which is x(x+2)(x-2) to get:
x^2(x-2) + 3x(x+2) = 7(x+2)(x-2)
x^3 - 2x^2 + 3x^2 + 6x = 7x^2 - 28
x^3 -6x^2 + 6x + 28 = 0
Graphing this I find a zero at x = -1.489362....
The other two zeroes are complex numbers.
