b) 4ab + 8ab – 6ab


c) -12wz + 7z² -4wz + 5w²z² + 3z² - 2w²z² - 4z


d) 15xy + 6xy³ - 2xy – 7xy³


e) 10x³y² + 7x³y – 5x³y² - 7x³y – 2 x³y²


f) -8abc + 20ab – 6a²b – 7ab – 15abc – 5a​

Answer 1

Explicação passo-a-passo:

a) 5x² + 3x + 7x²y – 3x² + 4x²y – x

2x²+2x+ 11x²y

b) 4ab + 8ab – 6ab

6ab

c) -12wz + 7z² -4wz + 5w²z² + 3z² - 2w²z² - 4z

10z-16wz+3w²z²

d) 15xy + 6xy³ - 2xy – 7xy³

13xy-1xy³

e) 10x³y² + 7x³y – 5x³y² - 7x³y – 2 x³y²

3x³y²-

f) -8abc + 20ab – 6a²b – 7ab – 15abc – 5a

-23abc+13ab-6a²b-5a
