-32=-6(3)-9

解答

- 32 = - 6 (3) - 9

假

求解步骤

- 32 = - 6 (3) - 9

化简

- 6 (3) - 9 : - 27

- 32 = - 27

两侧不相等

假

3 x (2 x + 3) = 2 x (x + 4.5) + 2

s im pl i f y \frac{1}{8} - \frac{1}{4} \cdot \frac{3}{2} + \frac{3}{5}

f a c t or 2 y^{2} - 3 y - 20

(x - 4) (x - 4) = 0

f a c t or 9 x^{3} - 13 x + 4
