$N = \frac{ { - 35x}^{14} + {42x}^{10} }{ {7x}^{7} } + \frac{ {40x}^{19} - {48x}^{15} }{ {8x}^{12} } \\ N = \frac{ { - 35x}^{14} }{ {7x}^{7} } + \frac{ {42x}^{10} }{ {7x}^{7} } + \frac{ {40x}^{19} }{ {8x}^{12} } - \frac{ {48x}^{15} }{ {8x}^{12} } \\ N = { - 5x}^{14 - 7} + {6x}^{10 - 7} + {5x}^{19 - 12} - {6x}^{15 - 12} \\ N = { - 5x}^{7} + {6x}^{3} + {5x}^{7} - {6x}^{3} \\ N = 0$
