vereinfachen (sqrt(x)-4)× (sqrt(x)+2)

Lösung

vereinfachen

(x - 4) \cdot (x + 2)

x - 2 x - 8

Schritte zur Lösung

(x - 4) (x + 2)

Apply FOIL method

(x - 4) (x + 2) : x - 2 x - 8

= x - 2 x - 8

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

e x p an d \frac{( 4 - 2 x ) ^{2} ( 1 + 2 x ) ^{2}}{( 1 - 3 x ) ^{3} ( 1 - x )}

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

e x p an d 3 (t + Δ t)^{2} (- sin (Δ t) + cos (Δ t))

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