Synthetic division is used since the equation is of the third degree. The divisors of -3 are 1, -1, 3, +3. So:
| 2 -7 8 -3
<u>1 | 2 -5 3</u>
| 2 -5 3 0
<u> 1 | 2 -3 </u>
2 -3 0
So the factorization is (x-1)² (2x-3)=0. So:


Synthetic division is used since the equation is of the third degree. The divisors of -4 are 1, -1, 2, -2, 4, -4. So:
| 1 -1 0 -4
<u>2 | 2 2 </u>
1 2 2 0
So the factorization is (x-2)(x²+x+2)=0 . When calculating the discriminant of the trinomial, it is concluded that it has no roots since the result is negative. So you only have one solution.


Synthetic division is used since the equation is of the third degree. The divisors of 2 are 1, -1, 2, -2. So:
| 6 7 9 2
<u>-2 | -12 10 -2</u>
6 -5 1 0
So the factorization is (x+2)(6x²-5x+1)=0 . The quadratic equation is solved by the general formula:

The correct answer is last option
surface area = 104 yd²
Step-by-step explanation:
Formula:
Surface area of cylinder = 2πr² + 2πrh
Where r is the radius and h is the height of cylinder
To find the surface area of cylinder
Here r = 4 yd and h = 9yd
Surface area = 2πr² + 2πrh = 2π * 4 * 4 + 2π *4 *9
= 32π + 72π = 104π yd²
Therefore the total surface area of given cylinder = 104π yd²
The correct answer is last option .
