(sixteen - three *x^ two)*(x - one * one)/(x^ three - sixteen *x)^ two + one /(x^ three - sixteen *x) = zero
(16 minus 3 multiply by x squared ) multiply by (x minus 1 multiply by 1) divide by (x cubed minus 16 multiply by x) squared plus 1 divide by (x cubed minus 16 multiply by x) equally 0
(sixteen minus three multiply by x to the power of two) multiply by (x minus one multiply by one) divide by (x to the power of three minus sixteen multiply by x) to the power of two plus one divide by (x to the power of three minus sixteen multiply by x) equally zero
