A)
${x}^{4} + {x}^{3} + {x}^{2} + {x}^{3} + {x}^{2} + x - 2 \\ = {x}^{4} + {2x}^{3} + {2x}^{2} + x - 2$
B)
${x}^{4} - {x}^{3} - {x}^{2} - {x}^{3} + {x}^{2} + x - 6 \\ = {x}^{4} - {2x}^{3} + x - 6$
C)
${x}^{4} - {3x}^{3} - {2x}^{2} - {3x}^{3} + {9x}^{2} + 6x \\ - 3 = {4}^{4} - {6x}^{3} + {7x}^{2} + 6x - 3$
D)
${4x}^{4} + {2x}^{3} - {8x}^{2} + {2x}^{3} + {x}^{2} - 4x \\ - 5 = {4x}^{4} + {4x}^{3} - {7x}^{2} - 4x - 5$
