因式分解 3am-8bp-2bm+12ap

解答

因式分解

3 am - 8 b p - 2 bm + 12 a p

(m + 4 p) (3 a - 2 b)

求解步骤

3 am - 8 b p - 2 bm + 12 a p

改写为

= 3 am - 8 b p - 2 bm + 4 \cdot 3 a p

因式分解出通项

3 a

= 3 a (m + 4 p) - 8 b p - 2 bm

改写为

= 3 a (m + 4 p) - 4 \cdot 2 b p - 2 bm

因式分解出通项

2 b

= 3 a (m + 4 p) - 2 b (4 p + m)

因式分解出通项

(m + 4 p)

= (m + 4 p) (3 a - 2 b)
