[tex]x^{2} – 3x – 5 = 0 Delta = (-3)^{2} – 4 cdot 1 cdot (-5) = 9 + 20 = 29 sqrt{Delta } = sqrt{29} x_{1} = dfrac{3 – sqrt{29} }{2} x_{2} = dfrac{3+ sqrt{29} }{2} boxed{x in left lbrace dfrac{3 – sqrt{29} }{2} , dfrac{3 + sqrt{29} }{2} right rbrace } [/tex]

Answer:The answer is B

Step-by-step explanation:I got it right
