In synthetic division we write only the coefficients of the dividend inside an upside-down division symbol. As we can clearly see from the picture given to us in the question, the coefficients of the dividend inside the upside-down division symbol are 2, 10, 1 and 5.
Now, from the given options, the only option that matches the given coefficients is the second option which is:
.
Thus, the second option,
, is the correct option.
3 x 5 is 15 multitply
Hope this helps!
