+x%5E4-1+.......I guess you need to simplify it and write as a product



+x%5E4-1+.......you can write x%5E4 as %28x%5E2%29%5E2 and 1 as 1%5E4=+%281%5E2%29%5E2
%28x%5E2%29%5E2-%281%5E2%29%5E2...now use the "difference of squares" formula
+%28x%5E2-1%5E2%29%28x%5E2%2B1%5E2%29+ ......use the "difference of squares" formula ones again
+%28x-1%29%28x%2B1%29%28x%5E2%2B1%29+
