Question

Resolva essa equação do 2 grau na formula de bhaskara 3x²+12x = 0

Answer 1

Bom dia

3x²+12x = 0
$\frac{-12+- \sqrt{12^2-4*3*0} }{2*3}= \frac{-12+-12}{6}$

x1= (-12+12)/6= 0/6= 0
x2= (-12-12)/6= -24/6= -4

Answer 2

3x²+12x = 0

Δ = 12² - 4.1.0 ==> 144-0 = 144

x= -12+/-12 ==> x = -12+/-0
          2.3                      6

x1= - 12+12 = 0
            6

x2= - 12-12 = - 4
            6
