Question

6) Reduza os termos semelhantes:
a) 7x – {5 - [3 + (4x – 8)]}
b) 5a³ - [ 3a - (a³ + 7a - 32³) + 6a³]
7) Determine o quociente e o resto:
a) x2 - 7x + 10 : (x - 2)
b) 2x³ + x² + 2x + 7: (2x² - x + 3)​

Answer 1

Explicação passo-a-passo:

6.a)

7x-(5-(3+4x-8))=7x-(5-3-4x+8)=7x-5+3+4x-8=11x-10

6.b)

5a3-(3a-a3+7a-32a3)+6a3=5a3-3a+a3-7a+32a3+6a3=44a3-10a

7.a)

x-6x-5=-5x-5

7.b)

x-x+2x+7/3=2x+7/3
