Step-by-step explanation:
x3 - 5x2 + 2x - 8
= —————————————————
x + 2
= x3 - 5x2 + 2x - 8
= 2x - 8
= x3 - 5x2
= (x - 4) • (2)
(x - 5) • (x2)
x3 - 5x2 + 2x - 8
("Dividend")
By : x + 2 ("Divisor")
dividend x3 - 5x2 + 2x - 8
- divisor * x2 x3 + 2x2
remainder - 7x2 + 2x - 8
- divisor * -7x1 - 7x2 - 14x
remainder 16x - 8
- divisor * 16x0 16x + 32
remainder - 40
Quotient : x2 - 7x + 16
Remainder : -40
