Refer to the image attached.
Since, we have to divide the polynomial
by (x+2) using synthetic division.
We will divide the coefficients 4 -2 3 by -2
First term = 4 will remain same.
Second term = 
So, second term = -10
Third term = 
So, third term = 23
So, 4 -10 23 is the correct answer
So, Option 2 is the correct answer.
