化简 2(n+1)

解答

化简

2 (n + 1)

2 n + 2

求解步骤

2 (n + 1)

使用分配律:

a (b + c) = ab + a c

2 (n + 1) = 2 n + 2 \cdot 1

= 2 n + 2 \cdot 1

数字相乘:

2 \cdot 1 = 2

= 2 n + 2

s im pl i f y \frac{2 tan ( x )}{1} - tan^{2} (x)

e x p an d (a + b) (2 a - 3 b)

s im pl i f y \frac{6}{2 x + 1} - \frac{x}{x + 3}

f a c t or 36 + x^{2} y^{2} - 9 y^{2} - 4 x^{2}

f a c t or a^{2} + 4 a
