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