Question

aplique a fórmula de bhaskara para resolver a equação x2+6x-1=0 determinando as raízes x1 e x2

Answer 1

x²+6x-1 = 0
delta = 6² - 4.1.(-1)
delta = 36 + 4
delta = 40

x = (-b+/-\/40)/2
x = (-6+/-\/4.10)/2
x = (-6+/-2\/10)/2
x = (-6/2)+/-(2\/10)/2
x = -3+/-\/10
x' = -3+\/10 --> x" = -3-\/10
