Question

−6x² − 5x + 1 = 0 resolva usando a formula de baskara

Answer 1

Resposta:

±$\frac{-b +/- \sqrt{b^{2} -4*a*c} }{2a} => \frac{-(-5 )+/- \sqrt{(-5)^{2} -4*-6*1} }{2*(6)}\\\\\frac{5+/- \sqrt{25 +24} }{-12} \\\frac{5+/- \sqrt{49} }{-12}\\\frac{5+/- 7 }{-12} \\\frac{-2 }{-12} = 0,17 ou \frac{1}{6} \\\frac{12 }{-12} = -1$
