two *(x*(tan(x)^ two + one)*tan(x) + tan(x)^ two + one) = zero
2 multiply by (x multiply by ( tangent of (x) squared plus 1) multiply by tangent of (x) plus tangent of (x) squared plus 1) equally 0
two multiply by (x multiply by ( tangent of (x) to the power of two plus one) multiply by tangent of (x) plus tangent of (x) to the power of two plus one) equally zero
2*(x*(tan(x)2 + 1)*tan(x) + tan(x)2 + 1) = 0
2*x*tanx2 + 1*tanx + tanx2 + 1 = 0
2*(x*(tan(x)² + 1)*tan(x) + tan(x)² + 1) = 0
2*(x*(tan(x) to the power of 2 + 1)*tan(x) + tan(x) to the power of 2 + 1) = 0
