Question

aplique a fórmula de Bhaskara 6x²+5x-1=o

Answer 1

6x² + 5x -1= 0


a= 6

b=5

c = -1



$x = \frac{ - b ± \sqrt{ {b}^{2} - 4ac} }{2.a}$


$x = \frac{ - 5± \sqrt{ {5}^{2} - 4.6. ( - 1) } }{2 \times 6}$


$x = \frac{ - 5± \sqrt{25 + 24} }{12}$


$x = \frac{ - 5 ± \sqrt{49} }{12}$


$x = \frac{ - 5 + 7}{12}$


$x1 = \frac{2}{12} = \frac{1}{6}$


$x2 = \frac{ - 5 - 7}{12} = - 1$
