f(x)(g(x))f(x)=4x-8,g(x)=6x-4

Lösung

f (x) (g (x)) f (x) = 4 x - 8, g (x) = 6 x - 4

36 \circ x^{2} f (x)^{2} - 48 \circ x f (x)^{2} + 16 \circ f (x)^{2}

Schritte zur Lösung

Finde

f (x) (g (x)) f (x) \circ g

gegeben

f (x) (g (x)) f (x) (x) = 4 x - 8, g (x) = 6 x - 4

f (x) (g (x)) f (x) \circ g = f (x) (g (x)) f (x) \circ g (x)

g (x) = 6 x - 4

g (x) = 6 x - 4

= f (x) (6 x - 4) f (x) \circ (6 x - 4)

Multipliziere aus

f (x) (6 x - 4) f (x) \circ (6 x - 4) : 36 \circ x^{2} f (x)^{2} - 48 \circ x f (x)^{2} + 16 \circ f (x)^{2}

= 36 \circ x^{2} f (x)^{2} - 48 \circ x f (x)^{2} + 16 \circ f (x)^{2}
