Let f(x)=x^4-3x^2+2 and g(x)=2x^4-6x^2+2x-1. What is the degree of f(x)*g(x)

f(x)=x-4-3x-2+2 und g(x)=2x-4-6x-2+2x-1. Wie hoch ist der Grad der f(x)*g(x)

 

Hallo Gast!

 

\(f(x)\times g(x)=(x-4-3x-2+2)\times (2x-4-6x-2+2x-1)=\color{blue}4x^2+22x+28\)

 

Es ergibt sich eine Funktion zweite Grades.

the degree of f(x) is 4

the degree of g(x) is  also 4

 

so the degree of the product will be 8
