因式分解 24k^4+12k^3-8k^2-4k

解答

因式分解

24 k^{4} + 12 k^{3} - 8 k^{2} - 4 k

4 k (2 k + 1) (3 k^{2} - 1)

求解步骤

24 k^{4} + 12 k^{3} - 8 k^{2} - 4 k

因式分解出通项

4 k : 4 k (6 k^{3} + 3 k^{2} - 2 k - 1)

= 4 k (6 k^{3} + 3 k^{2} - 2 k - 1)

因式分解

6 k^{3} + 3 k^{2} - 2 k - 1 : (2 k + 1) (3 k^{2} - 1)

= 4 k (2 k + 1) (3 k^{2} - 1)

6 - \frac{x}{3} = 3

f a c t or b^{3} + 216

f a c t or x^{3} + 4 x^{2} + 2 x + 8

1 - ∣ 3 p + 1 ∣ = - 3

- 2 (x + 6) + 2 = - 4 - (10 - 2 x)
