Explicación paso a paso:
a = 2
b = 4
c = -3
Formula general:
[tex]x = \frac{-b ±\sqrt{b^{2}-4ac }}{2a}[/tex]
[tex]x_{1,\:2}=\frac{-4\pm \sqrt{4^2-4\cdot \:2\left(-3\right)}}{2\cdot \:2}[/tex]
[tex]x=\frac{-2+\sqrt{10}}{2},\:x=-\frac{2+\sqrt{10}}{2}[/tex]
x₁ = 0.58113... x₂ = -2.58113...
x₁ = 0.58 , x₂ = -2.58
