化简 (sqrt(x)-xsqrt(x))(sqrt(x)-1)

解答

化简

(x - x x) (x - 1)

x - x - x^{2} + x x

求解步骤

(x - x x) (x - 1)

Apply FOIL method

(x - x x) (x - 1) : x - x - x^{2} + x x

= x - x - x^{2} + x x

e x p an d \frac{( D s ^{2} + P s + I ) \cdot 4865}{s ( s ^{2} + 497.8 s + 5951 )}

s im pl i f y (4 + x 2)^{2}

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

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

s im pl i f y - ((s - 2 t) (s^{2})) sin ((t^{2}) (s - 2 t))
