Another day — let's solve it.

Step 1: Identify the polynomial and the divisor. The polynomial is f(x)=x42x36x22x+1f(x) = x^4 - 2x^3 - 6x^2 - 2x + 1. The divisor is x+2x+2.

Step 2: Apply the Remainder Theorem. The Remainder Theorem states that if a polynomial f(x)f(x) is divided by xax-a, the remainder is f(a)f(a). In this case, the divisor is x+2x+2, which can be written as x(2)x - (-2). So, a=2a = -2. Therefore, the remainder is f(2)f(-2).

Step 3: Substitute x=2x = -2 into the polynomial f(x)f(x). f(2)=(2)42(2)36(2)22(2)+1f(-2) = (-2)^4 - 2(-2)^3 - 6(-2)^2 - 2(-2) + 1

Step 4: Calculate each term. (2)4=16(-2)^4 = 16 2(2)3=2(8)=16-2(-2)^3 = -2(-8) = 16 6(2)2=6(4)=24-6(-2)^2 = -6(4) = -24 2(2)=4-2(-2) = 4 +1+1

Step 5: Sum the calculated terms to find the remainder. f(2)=16+1624+4+1f(-2) = 16 + 16 - 24 + 4 + 1 f(2)=3224+4+1f(-2) = 32 - 24 + 4 + 1 f(2)=8+4+1f(-2) = 8 + 4 + 1 f(2)=13f(-2) = 13

The remainder is 1313.

The final answer is 13\boxed{13}.
