a)
%282x%5E-1%29+%2B+%284x%5E-1%29%2F+x if you have this
2%281%2Fx%29+%2B+%284%281%2Fx%29%29%2F+x
2%2Fx+%2B+%284%2Fx%29%2F+x
2%2Fx+%2B+4%2F%28x%2Ax%29
2%2Fx+%2B+4%2Fx%5E2%29
2x%2Fx%5E2+%2B+4%2Fx%5E2%29
%282x+%2B+4%29%2Fx%5E2%29
2%28x+%2B+2%29%2Fx%5E2%29


b)
+%282%5E%282x%29%29+-1%2F+%282%5Ex%29+%2B1
+4%5Ex+-2%5E%28-x%29+%2B1
