Find the constant coefficient when the polynomial 3(x - 4) - 2(x^2 - x + 7) + 5(x - 1) + 3(x + 8) is simplified.
+1224 \(3(x-4) - 2(x^2 - x + 7) + 5(x-1) + 3(x+8)\)
\((3x - 12) - (2x^2 - 2x - 14) + (5x - 5) + (3x + 24)\)
\(3x - 12 - 2x^2 + 2x + 14 + 5x - 5 + 3x + 24\)
\(-2x^2 + 13x + 21 \)
constant term = 21
