PROBLEMA Nº 01
Reduce: 5a + 12b – c + 3a – 8b – 4c 22a – 13ab + 50ab + 17a 4a + 3b – 2c – b – c + 2c – a 50x – 11y – 19 + 20x – 10 – 7y – 16m + 80n + 15 – 2m – 3n – 6m – 11 – 18x + 49y – 40z + 8y + 30x + x – 15y
PROBLEMA Nº 02
Reduce: 5a + 4b + 8c – (a + 2b + 2c) 6(x + y) + 3(x + y) – 9(x – y) 3(2x – 1) + 5(3x – 1) + 8(4x – 1) + 9 5x – [2x + y – (4x + y)] 8x + 2 – {(–2x + 3) + (–3x + 5)} 5x + 6y + [7x – 9y + z] - {x + y – z} 3(a + b) – 2(– a – b) + (–b + a) – (3a – b)
PROBLEMA Nº 03Sean:A = –7x4 + x3 – 2x – 7B = 4x3 + 6x2 – x + 1
C = –2x3 + x2 + 8x – 3Calcula:1) A – B 2) B – C3) (A + B) – C 4) (A – B) – (B – C)
