Question

Find the remainder when x^3-1 is divided by [x+1/2]

Answer 1

yes it's a reminder of tat polynomial

Answer 2

Heyaa...☺☺

Here is ur ans....

We can find the reminder by remainder theorem.

x+1/2, x = -1/2

$p(x) = {x}^{3} - 1 \\ \\ p( \frac{ - 1}{2} ) = { (\frac{ - 1}{2} )}^{3} - 1 \\ \\ p( \frac{ - 1}{2} ) = \frac{ - 1}{8} - 1 \\ \\ p( \frac{ - 1}{2} ) = \frac{ - 1 - 8}{8} \\ \\ p( \frac{ - 1}{2} ) = \frac{ - 9}{8}$

So the remainder is -9/8
