Question

х^2+6х-2=0 помогите решить пожалуйста

Answer 1

D=36+8= 44

x1= (-6+√44)/2= (-6+2√11)/2= -3+√11

x2= (-6-√44)/2= -3-√11

Answer 2

$x {}^{2} + 6x - 2 = 0 \ d = 6 {}^{2} + 4 times 2 = 36 + 8 = 44 = 2 sqrt{11} \ x _{1} = frac{ - 6 -2 sqrt{11} }{2} = - 3- sqrt{11} \ x_{2} = frac{ - 6 + 2 sqrt{11} }{2} = - 3 + sqrt{11}$
