解答

因式分解

{8 δ (x - 1)} (y)

8 yδ (x - 1)

求解步骤

(8 δ (x - 1)) (y)

去除括号:

(a) = a

= 8 δ (x - 1) y

e x p an d 112 (\frac{x ^{2}}{36} + \frac{y ^{2}}{27} = 1)

e x p an d \frac{5 ( s + 3 )}{( 6 s + 7 ) ( s ^{2} + 2 s + 6 )}

e x p an d \frac{- 2 ^{n - 1} n + 2 ^{n} n - 2 ^{n}}{2 ^{2 n - 1}}

e x p an d (x^{2} - 7)^{4} (2 x) d x

e x p an d \frac{8 ( 16 k ^{2} + 16 kn )}{3 n ^{3}}
