Fórmula Cuadrática
Ejercicio 1
\[5x^2 - x - 18=0\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}\]
Ejercicio 2
\[5x^2 - 2x - 51=0\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}\]
Ejercicio 3
\[5x^2 + 4x - 64=0\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}\]
\[x = \boxed{\phantom{\rule{2em}{1.2em}}}\]
