Question

Como é a forma fatorada desta expressão ?

Answer 1

6x² +5x + 1

∆= 25-24=1

x'= -5+1/12 = -4/12 = -1/3

x"= -5-1/12 = -6/12 = -1/2

a.(x -x').(x -x")

6.(x +1/3). (x +1/2)

3(x +1/3). 2(x +1/2)

(3x +1).(2x +1) ✓

Answer 2

Resposta:

6x² +5x + 1

∆= 25-24=1

x'= -5+1/12 = -4/12 = -1/3

x"= -5-1/12 = -6/12 = -1/2

a.(x -x').(x -x")

6.(x +1/3). (x +1/2)

3(x +1/3). 2(x +1/2)

(3x +1).(2x +1) ✓
