展开

(5, - 6) sin (x)

5 sin (x), - 6 sin (x)

求解步骤

(5, - 6) sin (x)

使用分配律:

a (b - c) = ab - a c

a = sin (x), b = 5,, c = 6

= sin (x) \cdot 5, - sin (x) \cdot 6

= 5 sin (x), - 6 sin (x)

e x p an d \frac{7 \cdot 2 ^{x} - 2 x - 6}{2 ( - x + 7 \cdot 2 ^{x} - 4 )}

e x p an d \frac{5 s ^{2} + 732}{( s ^{2} + 144 ) ( s + 2 )}

e x p an d \frac{- 2 s + 8}{s ( s + 1 )}

e x p an d \frac{( 4 x - 5 ) d x}{( 2 x + 1 ) ^{3} ( x - 3 ) ^{3}}

e x p an d \frac{( 8 + y ) ( 4 ) - ( 4 x )}{( 8 + y ) ^{2}}
