因式分解 6a^3+39a^2+45a

解答

因式分解

6 a^{3} + 39 a^{2} + 45 a

3 a (2 a + 3) (a + 5)

求解步骤

6 a^{3} + 39 a^{2} + 45 a

因式分解出通项

3 a : 3 a (2 a^{2} + 13 a + 15)

= 3 a (2 a^{2} + 13 a + 15)

因式分解

2 a^{2} + 13 a + 15 : (2 a + 3) (a + 5)

= 3 a (2 a + 3) (a + 5)

\frac{1}{2} x + \frac{1}{3} x - \frac{1}{5} (x + 7) \leq \frac{1}{10}

- 6 \leq 3 (6 - 4 x)
