展开 (3x-y^2+1)dx

解答

展开

(3 x - y^{2} + 1) d x

3 x d x - y^{2} d x + d x

求解步骤

(3 x - y^{2} + 1) d x

打开括号

= d x \cdot 3 x + d x (- y^{2}) + d x \cdot 1

使用加减运算法则

+ (- a) = - a

= 3 x d x - y^{2} d x + 1 \cdot d x

乘以:

1 \cdot d x = d x

= 3 x d x - y^{2} d x + d x

e x p an d V (- 4, - 3) \cdot P (- 7, - 6)

e x p an d \frac{t ^{2} - 1}{( t ^{2} + 1 ) ^{2}}

e x p an d Q (- 5, 3) (3, - 2)

e x p an d \frac{5 ( - 3 s - 8 )}{s + 3}

e x p an d 510 \cdot (\frac{π}{30})
