化简 6m^2n-14mn^2-mn^2+2m^2n

解答

化简

6 m^{2} n - 14 m n^{2} - m n^{2} + 2 m^{2} n

解答

8 m^{2} n - 15 m n^{2}

求解步骤

6 m^{2} n - 14 m n^{2} - m n^{2} + 2 m^{2} n

同类项相加:

- 14 m n^{2} - m n^{2} = - 15 m n^{2}

= 6 m^{2} n - 15 m n^{2} + 2 m^{2} n

对同类项分组

= 6 m^{2} n + 2 m^{2} n - 15 m n^{2}

同类项相加:

6 m^{2} n + 2 m^{2} n = 8 m^{2} n

= 8 m^{2} n - 15 m n^{2}

流行的例子

11 h + 9 \leq 5 h - 21

因式分解 16x^2-6x^3

f a c t or 16 x^{2} - 6 x^{3}

- 3 \leq x + 2 \leq 8

化简 243^{6/5}

s im pl i f y 24 3^{\frac{6}{5}}

(x-1)/(x^3+1)>= 0

\frac{x - 1}{x ^{3} + 1} \geq 0
