Explicación paso a paso:
a = 3
b = 5
c = -3
Formula general :
[tex]x= \frac{-b±\sqrt{b^{2} -4ac}}{2a}[/tex]
[tex]x_{1,\:2}=\frac{-5\pm \sqrt{5^2-4\cdot \:3\left(-3\right)}}{2\cdot \:3}[/tex]
x₁ = [tex]\frac{-5+\sqrt{61}}{6}[/tex] x₂ = [tex]\frac{-5-\sqrt{61}}{6}[/tex]
x₁ = 0.46837... x₂ = -2.13504...
x₁ = 0.47 ; x₂ = -2.14
