Explicación paso a paso:
Formula general = [tex]\frac{-b +/-\sqrt{b^{2}-4(a)(c) } }{2(a)}[/tex]
resolviendo:
2x² + 9x + 10 = 0 ----> a = 2 , b = 9 , c = 10
------------------------------------------------------------------------
[tex]\frac{-9 +/-\sqrt{9^{2}-4(2)(10) } }{2(2)}[/tex]
[tex]\frac{-9 +/-\sqrt{81-80 } }{4}[/tex]
[tex]\frac{9+-(1)}{4}[/tex]
hallamos las dos soluciones
[tex]x_{1} = \frac{9+1}{4} = \frac{5}{2}[/tex]
[tex]x_{2}= \frac{9-1}{4}= 2[/tex]
