$Answer \\ we \: know \: that \: \\ (x + y + z) {}^{2} = x {}^{2} + y { }^{2} + z {}^{2} + 2xy + 2yz + 2xz \\ \\ 4x {}^{2} + 9y {}^{2} + 16z { }^{2} + 12xy - 24yz - 16xz \\ = (2x) {}^{2} + (3y) {}^{2} + ( - 4z) {}^{2} + 2 \times 2x \times 3y + 2 \times 3y \times ( - 4z) + 2 \times 2x \times ( - 4z) \\ = (2x + 3y - 4z) {}^{2}$

Hope it helps.
