thirty-two *(tan(four *x)^ two - one)*(three *tan(four *x)^ two + one) = zero
32 multiply by ( tangent of (4 multiply by x) squared minus 1) multiply by (3 multiply by tangent of (4 multiply by x) squared plus 1) equally 0
thirty minus two multiply by ( tangent of (four multiply by x) to the power of two minus one) multiply by (three multiply by tangent of (four multiply by x) to the power of two plus one) equally zero
32*(tan(4*x)2 - 1)*(3*tan(4*x)2 + 1) = 0
32*tan4*x2 - 1*3*tan4*x2 + 1 = 0
32*(tan(4*x)² - 1)*(3*tan(4*x)² + 1) = 0
32*(tan(4*x) to the power of 2 - 1)*(3*tan(4*x) to the power of 2 + 1) = 0
