Answer:


(2x^3+2)/(x+3)=2x^2-6x+18-(52)/((x+3))

Step-by-step explanation:

To solve the expression using synthetic division, we will need to identify the coefficients of the dividend, so:

2x³ + 2 = 2x³ + 0x² + 0x + 2

Therefore, the coefficients are 2, 0, 0, an 2.

Additionally, since the dividend is (x + 3), which is equal to (x - (-3)) we will use the number -3.

Then, the synthetic division will be:

Where the first 2 is just moving down, then we calculate:

2 x (-3) = -6 and add then to the next coefficient.

In the same way, we get:

-6 x (-3) = 18

18 x (-3) = -54

Finally, 2 + (-54) = -52

So, the first three numbers are the coefficients of the quotient and the last number is the remainder.

Therefore, the answer to the expression is:


(2x^3+2)/(x+3)=2x^2-6x+18-(52)/((x+3))
