展开

10 + (1 - 2) i

10 + i (1 - 2)

求解步骤

10 + (1 - 2) i

= 10 + i (1 - 2)

乘开

i (1 - 2) : i (1 - 2)

= 10 + i (1 - 2)

e x p an d \frac{( x - 9 )}{( - 8 x + 2 ) ( 5 x + 4 )}

e x p an d \frac{2 ( 3 x - 4 )}{3 x ^{2} - 8 x + 6}

e x p an d (t - 3) (s^{2} + 4)^{^{'}}

e x p an d (e + 12)^{2}

e x p an d \frac{2 x + 3}{( x + 1 ) ( s ^{2} + 5 s + 6 )}
