two *x*(x^ two *(four *x^ two /(x^ two + one) - one)/(x^ two + one) - six *x^ two /(x^ two + one) + three)/(x^ two + one) = zero
2 multiply by x multiply by (x squared multiply by (4 multiply by x squared divide by (x squared plus 1) minus 1) divide by (x squared plus 1) minus 6 multiply by x squared divide by (x squared plus 1) plus 3) divide by (x squared plus 1) equally 0
two multiply by x multiply by (x to the power of two multiply by (four multiply by x to the power of two divide by (x to the power of two plus one) minus one) divide by (x to the power of two plus one) minus six multiply by x to the power of two divide by (x to the power of two plus one) plus three) divide by (x to the power of two plus one) equally zero
2*x*(x to the power of 2*(4*x to the power of 2/(x to the power of 2 + 1) - 1)/(x to the power of 2 + 1) - 6*x to the power of 2/(x to the power of 2 + 1) + 3)/(x to the power of 2 + 1) = 0
