(11x² -2 - x + 10x³) ÷ (5x - 2)
(-x³ - x² + 2x + 1) (-1/2 x )

Answer 1

(11x² -2 - x + 10x³) ÷ (5x - 2) ==. (10x³ + 11x² - x - 2 ) ÷ (5x - 2) 


          |10  11 - 1  - 2
   2/5  |10   15  5    0  

raiz ==> 5x - 2 = 0 ==> x = 2/5
===============================================

2.10+11 = 4+11 = 15
5

2.15-1 = 6-1 = 5
5

2.5-2 = 2-2 = 0
5               
======================================================
Q(x) =  10x² + 15x + 5

R(x) = 0

(-x³ - x² + 2x + 1) (-1) =  x³ +  x² - 2x - 1
                            2x              2x
