因式分解 18m^2-39m+18

解答

因式分解

18 m^{2} - 39 m + 18

3 (3 m - 2) (2 m - 3)

求解步骤

18 m^{2} - 39 m + 18

因式分解出通项

3 : 3 (6 m^{2} - 13 m + 6)

= 3 (6 m^{2} - 13 m + 6)

因式分解

6 m^{2} - 13 m + 6 : (3 m - 2) (2 m - 3)

= 3 (3 m - 2) (2 m - 3)

x^{2} + x < 20

f a c t or \frac{( x - 4 - 3 )}{( x - 13 )}

y - 9 \geq 11

2 x^{2} + 16 x + 24 = 0
