(2 - 3) (x - 1)

x (2 - 3) + 3 - 2

求解步骤

(2 - 3) (x - 1)

Apply FOIL method

(2 - 3) (x - 1) : x (2 - 3) + 3 - 2

= x (2 - 3) + 3 - 2

e x p an d (2 e^{- \frac{t}{100}} - e^{- \frac{t}{50}})^{3}

e x p an d (3 + sin (x))^{2}

s im pl i f y (- 3 - 3 i)^{5}

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

e x p an d \frac{1}{( 1 + t ^{2} ) ( 1 + r ^{2} )}
