Answer:
2x³ + 10x² + x + 5
Step-by-step explanation:
The coefficients of the dividend are represented by the top row, that is
2 10 1 5 → 2x³ + 10x² + x + 5
The divisor is ( x + 5) and
the quotient is represented by the first 3 numbers on the bottom row
2 0 1 → 2x² + 1
The last zero on the same row is the remainder
Since zero this indicates that (x + 5) is a factor of 2x³ + 10x² + x + 5
