erweitern pi(x)^2(3x+1)

Lösung

erweitern

π (x)^{2} (3 x + 1)

3 π x^{3} + π x^{2}

Schritte zur Lösung

π (x)^{2} (3 x + 1)

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = π (x)^{2}, b = 3 x, c = 1

= π (x)^{2} \cdot 3 x + π (x)^{2} \cdot 1

= 3 π (x)^{2} x + 1 π (x)^{2}

Vereinfache

3 π (x)^{2} x + 1 π (x)^{2} : 3 π x^{3} + π x^{2}

= 3 π x^{3} + π x^{2}

e x p an d x \cdot x^{2}
