Question

Simplifique:

a) 10a²
_______
5a

b) - 6ab
______
48b²

c) -3x(x + 1)
_________
- 2(x + 1)​

Answer 1

Explicação passo-a-passo:

a) 10a²

_______

5a

10a²/5a=10/5.(a²/a)

10a²/5a=2.(a)

10a²/5a=2a

b) - 6ab

______

48b²

-6ab/48b²=-6/48.(ab/b²)= -1/8.(a/b)

-6ab/48b²= - a/8b

c) -3x(x + 1)

_________

- 2(x + 1)

[-3x.(x+1)]/[2.(x+1)]=-3x/2.[(x+1)/(x+1)]=

[-3x.(x+1)]/[2.(x+1)]=-3x/2.(1)= -3x/2
