Answer 1

1) Reduza os termos semelhantes

a)5×-6×+7×-8×+9-10× = 12x + 9

b)5a-2b+4a-7b-9a+8b-5a+3b = -5a + 4b

c) 5ײ-3×+2-4ײ+5×-1+4ײ-3×+7 = 5x^2 -5x +8

d)׳-4ײ-5×+6-5׳+6-5׳+4ײ-5×+7 = ×^3 -10× +19

e)×⁴-5׳+4ײ-3+2×⁴+3׳-6ײ-7×+8 = 3x^4 -2x^3 -2x^2 - 7x +5

f)a²-2ab+b²+5a²-3ab-7b² = 6a^2 - 5ab^2 -6^2

g) 5×-4y+4×-7y-8×+ay-5× = -4x -11y + ay

h)ײ-5×+4-ײ+5×+8 = 12
