Question

Rozwiąż:

W(x)=-6x+3

P(x)=x²+2x-1

Q(x)=5x³+x+4

⅓W(x)(P(x)-Q(x))

Answer 1

⅓W(x)(P(x)-Q(x)) =1/3 * (-6x+3) [ (x²+2x-1) - (5x³+x+4) ] =

 

(-2x + 1) * [ x² + 2x - 1 - 5x³ - x - 4  ] =(1 - 2x) * [ x² + x  - 5x³  - 5 ] =

 

x² + x  - 5x³  - 5 - 2x³ - 2x² + 10x^4 + 10x = 10x^4 - 7x³ - x² + 11x - 5
