(2 + x - 1) (2 + x - 1)

x - 2 2 + x + 3

求解步骤

(2 + x - 1) (2 + x - 1)

Apply FOIL method

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

= x - 2 2 + x + 3

e x p an d lo g_{10} (x^{9} y^{- 8})

e x p an d e^{- 5 (x + 1)} \cdot δ (x - 3) + cos (5 \cdot π \cdot x) \cdot δ (x - 4)

e x p an d (x^{3} - \frac{1}{x ^{6}})^{6}

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

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