Question

necesito que ayuden a resolver esta ecuacion cuadratica 30x2 + 19x -5 = 0

Answer 1

Aplicando la fórmula general
 
                  $x= \frac{-b+/- \sqrt{b^2-4.a.c} }{2a} \\ \\ x= \frac{-19+/- \sqrt{19^2-4.30.(-5)} }{2.30} \\ \\ x= \frac{-19+/-31}{60} \\ \\ x= \frac{-19-31}{60} \\ \\ x1= -\frac{5}{6} \\ \\ x= \frac{-19+31}{60} \\ \\ x2= \frac{1}{5}$
 
                   S = {$- \frac{5}{6} , \frac{1}{5}$}
