16 x^{4} - 1

求解步骤

(4 x^{2} - 1) (4 x^{2} + 1)

Apply Difference of Two Squares

(4 x^{2} - 1) (4 x^{2} + 1) : 16 x^{4} - 1

= 16 x^{4} - 1

s im pl i f y \frac{2 x ^{4} - 3 x ^{4} + 3 x ^{2}}{x ^{6}}

s im pl i f y \frac{( a ^{3} - 2 a ^{2} \cdot b )}{( 2 a ^{3} \cdot b ^{2} - a ^{4} \cdot b )}

s im pl i f y \frac{1}{2} + \frac{1}{2} + 4 + 6 + \frac{1}{2} + 4 + 6 + 8 + \frac{1}{2} + 4 + 6 + 8 + 2 n
