(2 + 3) (6 - 2)

12 - 22 + 63 - 6

十进制

17.11438 \dots

求解步骤

(2 + 3) (6 - 2)

Apply FOIL method

(2 + 3) (6 - 2) : 12 - 22 + 63 - 6

= 12 - 22 + 63 - 6

\frac{d}{d θ} ((x (θ)) (θ - sin (θ)))

e x p an d (e^{x} sin (2 x)) (e^{x} cos (2 x) - 2 e^{x} sin (2 x))

e x p an d - 2 (4 e^{- x^{2}} x^{3} - 6 e^{- x^{2}} x)

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

e x p an d (x + 5) l e f t (x - 5)
