- sixteen *(four *x^ two /(x^ two - sixteen) - one)/(x^ two - sixteen)^ two = zero
minus 16 multiply by (4 multiply by x squared divide by (x squared minus 16) minus 1) divide by (x squared minus 16) squared equally 0
minus sixteen multiply by (four multiply by x to the power of two divide by (x to the power of two minus sixteen) minus one) divide by (x to the power of two minus sixteen) to the power of two equally zero
