Answer 1

$a) \: 9x {}^{2} - 4x - 3x {}^{2} + 3x \\ 9x {}^{2} - 3x {}^{2} - 4x + 3x \\ 6x {}^{2} - x. \\ \\ b) \: x + 7 +x - 10 - 1 \\ x + x + 7 - 10 - 1 \\ 2x - 3 - 1 \\ 2x - 4. \\ \\ c) \: x {}^{3} - x {}^{2} + 7x {}^{2} + 10x {}^{3} + 4 \\ x {}^{3} + 10x {}^{3} - x {}^{2} + 7x {}^{2} + 4 \\ 11x {}^{3} + 6x {}^{2} + 4. \\ \\ d) \: 2x {}^{3} - 7x { }^{2} + 4x - 2 + 8 - 3x {}^{2} \\ 2x {}^{3 } - 7x {}^{2} - 3x {}^{2} + 4x - 2 + 8 \\ 2x {}^{3} - 10x {}^{2} + 4x + 6. \\ \\ e) \: 4a {}^{2} x - 3x {}^{2} - 6x { }^{2} - 2a {}^{2} x - 1 \\ 4a {}^{2} x - 2a {}^{2}x - 3x { }^{2} - 6x {}^{2} - 1 \\ 2a {}^{2} x - 9x {}^{2} - 1.$
