Question

resolver a equačão (3× + 1).(3× + 1) = 0

Answer 1

Resposta:

-1/3

Explicação passo a passo:

(3x+1) . (3x+1) = 0

3x.3x+3x.1+1.3x+1.1=0

9x²+3x+3x+1=0

9x²+6x+1=0

Δ=b²-4ac

Δ=6²-4.9.1

Δ=36-36

Δ=0

-b±√Δ÷2a

- (6) ±√0÷2.9 =

-6 + 0 / 18 = -6/18 = -3/9 = -1/3 ou -6-0/18 = -6/18 =-3/9=-1/3

Resposta: -1/3
