展开 3(x-4=-1-(3x-1))

解答

展开

3 (x - 4 = - 1 - (3 x - 1))

3 x - 12 = - 9 x

求解步骤

3 (x - 4 = - 1 - (3 x - 1))

打开括号

= 3 x + 3 (- 4 =) + 3 (- 1) + 3 (- (3 x - 1))

使用加减运算法则

+ (- a) = - a

3 x - 3 \cdot 4 = - 3 \cdot 1 - 3 (3 x - 1)

化简

3 x - 3 \cdot 4 = - 3 \cdot 1 - 3 (3 x - 1) : 3 x - 12 = - 9 x

3 x - 12 = - 9 x

e x p an d e^{e^{(1 + x)^{2}}}

e x p an d (1 - x^{3}) (e^{0.05 x})

e x p an d T (p (x) = 2 p (x) - p (2 x))

e x p an d 0.015 \cdot (3.44 - 106.4 x + 867 x^{2} - 1264 x^{3})^{2}

e x p an d 2584.72 \cdot (x + y - 0.08)^{2}
