Step-by-step explanation:
[tex] \frac{16 {x}^{4} - 28 {x}^{3} + 8x }{4x} = \\ \frac{16 {x}^{4} }{4x} - \frac{ 28{x}^{3} }{4x} + \frac{8x}{4x} = \\ ( \frac{16}{4} \times \frac{ {x}^{4} }{x} ) - ( \frac{28}{7} \times \frac{ {x}^{3} }{x} ) + ( \frac{8}{4} \times \frac{x}{x} ) = \\ 4 {x}^{3} - 7 {x}^{2} + 2[/tex]
