Answer:
 x²  -x + 1  Quotient
Step-by-step explanation:
Given in the question,
the numerator = x^4 + x³ + 7x² - 6x + 8
the denominator = x² + 2x + 8
Polynomial Long Division
Dividing :
x^4+x^3+7x^2-6x+8 Â ("Dividend")
By :
 x2+2x+8   ("Divisor")
                                 x²  -x + 1            Quotient
                              -------------------------------
dividend      x² + 2x + 8   | x^4 +  x^3 +  7x² -6x + 8
divisor  *x²                  x^4 + 2x^3 + 8x²
   Â
remainder                          -x³  - x²  -6x + 8
divisor  * -x1                        -x³  -2x² . -8x Â
Â
remainder                              x²  +2x  +8
divisor  *1                               x²  +2x  +8
remainder                                      0
B)
(x²  -x + 1)   (x² + 2x + 8)  Â
= x^4 +  x^3 +  7x² -6x + 8
hence provedÂ
