4 x + 3 y \cdot 4 x - 3 y

4 x + 12 x y - 3 y

求解步骤

4 x + 3 y \cdot 4 x - 3 y

数字相乘:

3 \cdot 4 = 12

= 4 x + 12 x y - 3 y

e x p an d \frac{5 ( 18 - 3 y )}{2}

e x p an d (1 - \frac{3 - i}{2})^{24}

e x p an d \frac{d}{d x} (x (x - 4)^{3}) + 2

e x p an d \frac{1}{( x + 7 ) ^{3}}

e x p an d \frac{b}{( 1 - a ) ( 1 - b ) ^{2}}
