The values "1 -13 -48" represents the polynomial x² - 13x - 48.
The value "-3" represents the polynomial "x + 3" (the value -3 is the zero of this polynomial).
Now, calculating the synthetic division, we have:
The result (quotient) of the division is "1 -16 0", which represents the polynomial x - 16 and the remainder is 0.
Therefore the answer is
