因式分解 (1-a^2)(1-b^2)-4ab

解答

因式分解

(1 - a^{2}) (1 - b^{2}) - 4 ab

(a + 1) (a - 1) (b + 1) (b - 1) - 4 ab

求解步骤

(1 - a^{2}) (1 - b^{2}) - 4 ab

(1 - a^{2}) (1 - b^{2}) = (a + 1) (a - 1) (b + 1) (b - 1)

= (a + 1) (a - 1) (b + 1) (b - 1) - 4 ab

f a c t or e^{30} - 1

f a c t or tan^{2} (x) - 5 tan (x) + 6

\frac{d ^{2}}{d x ^{2}} ((y) (e^{x}))

f a c t or 3 - 16 x^{7}

f a c t or 3 x + 2 x z - 21 y - 14 yz
