Question 4602
{{{5x+5/x-2*2x^2-8x+8/x^2-1}}}

Using the order of operations:
there are no parentheses
there are no exponents to work
multiplication/division occurs from left to right (multiply {{{2x^2}}} by 2):
{{{5x+5/x-4x^2-8x+8/x^2-1}}}
Addition subtraction occurs from left to right (Combine the x terms):
{{{-3x+5/x-4x^2+8/x^2-1}}}
Then just put it in descending degree order:
{{{-4x^2-3x+5/x+8/x^2-1}}}
