因式分解 (x+8)6-2(x+8)5

解答

因式分解

(x + 8) 6 - 2 (x + 8) 5

- 4 (x + 8)

求解步骤

(x + 8) \cdot 6 - 2 (x + 8) \cdot 5

数字相乘:

2 \cdot 5 = 10

= 6 (x + 8) - 10 (x + 8)

因式分解出通项

2 (x + 8)

= 2 (x + 8) (3 - 5)

化简

3 - 5 : - 2

= - 2 \cdot 2 (x + 8)

整理后得

= - 4 (x + 8)

f a c t or \frac{- 3 - 3 5}{2}

f a c t or ln (2) (x)

f a c t or 2^{x + 1} + 5 \cdot 2^{x}

f a c t or 529 - \frac{676}{841}

f a c t or \frac{54 + 9 3}{23}
