**Step 1: Compute $$f(-1)$$**
$$
f(-1) = (-1)^2 + 8(-1) + 1 = 1 - 8 + 1 = -6
$$

**Step 2: Compute $$f(4)$$**
$$
f(4) = 4^2 + 8(4) + 1 = 16 + 32 + 1 = 49
$$

**Step 3: Compute $$f(-1) + f(4)$$**
$$
f(-1) + f(4) = -6 + 49 = 43
$$

**Step 4: Compute $$f(-1) - f(4)$$**
$$
f(-1) - f(4) = -6 - 49 = -55
$$
$$ f(-1) + f(4) = 43 $$ $$ f(-1) - f(4) = -55 $$
