Explicación paso a paso:
[tex]5x^{2} +8x-3=0[/tex]
[tex]a = 5 ; b = 8 ; c = -3[/tex]
Fórmula general:
[tex]x = \frac{-b\frac{+}{}\sqrt{b^{2}-4ac } }{2a}[/tex]
[tex]x= \frac{-8\frac{+}{}\sqrt{8^{2} -4(5)(-3)} }{2(5)} =\frac{-8\frac{+}{}\sqrt{64+60} }{10} =\frac{-8\frac{+}{}\sqrt{124} }{10} = \frac{-8\frac{+}{}2\sqrt{31} }{10} = \frac{4\frac{+}{} \sqrt{31} }{5}[/tex]
[tex]x_{1} = \frac{-4+\sqrt{31} }{5} = 0.31[/tex] ; [tex]x_{2} = \frac{-4-\sqrt{31} }{5} = -1.91[/tex]
