What is the result of dividing 2x^3-3x^2-17x+30 by x+3

Using long division;
Dividing ; 2x³- 3x² -17x -30 (Dividend)

BY : x+3 ( Divisor)
     dividend : 2x³- 3x² -17x -30
 
- divisor * 2x²  2x² + 6x²
 Remainder            - 9x² -17x -30
divisor * -9x            - 9x² - 27x
Remainder                       10x - 30
Divisor  * 10x^0                10x + 30
Remainder                                - 60
 Thus;
The  Quotient is 2x² -9x +10
Remainder is - 60

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2
