- thirty-two *(four *x - one)/((four *x - one)^ two + one)^ two = zero
minus 32 multiply by (4 multiply by x minus 1) divide by ((4 multiply by x minus 1) squared plus 1) squared equally 0
minus thirty minus two multiply by (four multiply by x minus one) divide by ((four multiply by x minus one) to the power of two plus one) to the power of two equally zero
-32*(4*x - 1)/((4*x - 1)2 + 1)2 = 0
-32*4*x - 1/4*x - 12 + 12 = 0
-32*(4*x - 1)/((4*x - 1)² + 1)² = 0
-32*(4*x - 1)/((4*x - 1) to the power of 2 + 1) to the power of 2 = 0
