erweitern (4a^{1/2}+3)(2a^{1/2}-1)

Lösung

erweitern

(4 a^{\frac{1}{2}} + 3) (2 a^{\frac{1}{2}} - 1)

8 a + 2 a^{\frac{1}{2}} - 3

Schritte zur Lösung

(4 a^{\frac{1}{2}} + 3) (2 a^{\frac{1}{2}} - 1)

Apply FOIL method

(4 a^{\frac{1}{2}} + 3) (2 a^{\frac{1}{2}} - 1) : 8 a + 2 a^{\frac{1}{2}} - 3

= 8 a + 2 a^{\frac{1}{2}} - 3
