The remainder represented by synthetic division is -5.
A vertical line and a horizontal line combine to make an L shape.
There are two rows of entries within the shape.
Row 1 has entries 2, 10, 1, 5.
Row 2 has entries blank, -10, 0, -5.
Synthetic division can be defined as a simplified way of dividing a polynomial with another polynomial equation of degree 1.
Entry -5 is on the outside to the left of the shape.
The entry represents the zero of the divisor.
This entry to the variable (assume the variable is x) is;
[tex]\rm x=-5\\\\x+5=0[/tex]
Hence, the divisor of the synthetic division is -5.
