Question

find the reminder when x³-3x²-3x-1 is divide by (x-1)​

Answer 1

Answer:

-6

Step-by-step explanation:

$let \: p(x) = {x}^{3} - 3 {x}^{2} - 3x - 1 \\ let \: f(x) = x - 1 \\ = > 0 = x - 1 \\ = > x = 1$

By substituting x in p(x),

${(1)}^{3} - 3 {(1)}^{2} - 3 \times 1 - 1 \\ = 1 - 3 \times 1 - 3 \times 1 - 1 \\ = 1 - 3 - 3 - 1 \\ = - 6$

This is by remainder theorem.
