It's a straight forward long division
............ x^2 + 4x + 5
......._______________________
x + 4 ) x^3 + 8x^2 + 21x + 20
............-x^3 - 4x^2
............___________
.........................4x^2 + 21x
........................-4x^2 - 16x
........................____________
........................................5x + 20
.......................................-5x - 20
