Answer:

2x²+10x-5

Explanation:

Given polynomial: 2x³ + 4x² - 35x + 15

Divisor: x - 3

Step 1: Bring down the coefficient of the highest power of x:

2

Step 2: Multiply the divisor, 3, by the value just brought down (2):

2 * 3 = 6

Step 3: Add the result to the next coefficient in the polynomial (4):

6 + 4 = 10

Step 4: Multiply the divisor, 3, by the new sum (10):

10 * 3 = 30

Step 5: Add the result to the next coefficient in the polynomial (-35):

30 - 35 = -5

Step 6: Multiply the divisor, 3, by the new sum (-5):

-5 * 3 = -15

Step 7: Add the result to the last coefficient in the polynomial (15):

-15 + 15 = 0

The resulting coefficients after synthetic division are: 6, 10, -5, 0.

Therefore, the quotient is 2x² + 10x - 5.

Answer:

D) 2x²+10x-5

Explanation:

3 | 2 4 -35 15

_____6_ 30 -15___

2 10 -5 | 0

Therefore, (2x³+4x²-35x+15)/(x-3) = 2x²+10x-5
