the remainder is
question help: video read written example
Step1: Identify root & coefficients
Root of divisor $x-2$ is $2$.
Coefficients of dividend: $1$ (for $x^3$), $2$ (for $x^2$), $0$ (for $x$), $-19$ (constant)
Step2: Set up synthetic division
2 | 1 2 0 -19
2 8 16
---------------
1 4 8 -3
Step3: Extract quotient & remainder
Quotient uses first 3 results, degree reduced by 1.
Remainder is last result.
