Answer

So, the quotient is \(-2x^2 + 4x - 6\) and the remainder is 17.

Steps

Step 1 :Write down the coefficients of the polynomial we are dividing, which are -2, 0 (since there is no \(x^2\) term), 2, and 1. Also write down the root of the divisor, which is -2 (since \(x + 2 = 0\) when \(x = -2\)).

Step 2 :Set up the synthetic division table as follows: \[-2 | -2 0 2 1\]

Step 3 :Perform the synthetic division: \[-2 | -2 0 2 1\] \[ | 4 -8 16\] \[-----------------\] \[ | -2 4 -6 17\]

Step 4 :The numbers on the bottom row are the coefficients of the quotient and the remainder. The quotient is \(-2x^2 + 4x - 6\), and the remainder is 17.

Step 5 :So, the quotient is \(-2x^2 + 4x - 6\) and the remainder is 17.
