Question

f(x)=x° ( x+1 ) •(x - 2 ) • (x-3 ) me ajuda com essa conta

Answer 1

F(x)=x° ( x+1 ) •(x - 2 ) • (x-3 )

F(x)= 1.( x+1 ) •(x - 2 ) • (x-3 )

F(x) =  x³ - 4x² + x + 6

====================================================
( x+1 ) •(x - 2 ) • (x-3 ) =

( x+1 ) •(x - 2 ) = x² - 2x + x - 2 ==> x² - x - 2


(x² - x - 2)(x - 3) = x³ - x² - 2x - 3x² + 3x + 6 ==> x³ - 4x² + x + 6
