因式分解 x(b+c)+3b+3c

解答

因式分解

x (b + c) + 3 b + 3 c

(b + c) (x + 3)

求解步骤

x (b + c) + 3 b + 3 c

因式分解

3 b + 3 c : 3 (b + c)

= x (b + c) + 3 (b + c)

因式分解出通项

b + c

= (b + c) (x + 3)

s im pl i f y \frac{( 19 ) 13. 5 ^{2}}{32.8523}

3 (x - 7) < 2 (2 x - 1)

- x = - 18

- 2 = - x + x^{2} - 4

\frac{3}{5} x \leq 4
