vereinfachen (sqrt((u+4))-3)(sqrt((u+4))+3)

Lösung

vereinfachen

((u + 4) - 3) ((u + 4) + 3)

u - 5

Schritte zur Lösung

(u + 4 - 3) (u + 4 + 3)

Apply rule:

(a) = a

(u + 4) = u + 4

= (u + 4 - 3) (u + 4 + 3)

Apply Difference of Two Squares

(u + 4 - 3) (u + 4 + 3) : u - 5

= u - 5

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

e x p an d (x + 2 \cdot lo g_{2} (x)) (x - 2)

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

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

e x p an d (2 u, 2 v, 1) \cdot (9 - u^{2} - v^{2}, 9 - u^{2} - v^{2}, u)
