Answer:

[tex]x=\frac{-5+\sqrt{33} }{2}[/tex] and [tex]x=\frac{-5-\sqrt{33} }{2}[/tex]

Step-by-step explanation:

x = [-b±√(b²-4ac)]/2a

x = [-(-5)±√((-5)²-4(1)(-2))]/2(1)

x = [5±√(25+8)]/2

x= [-5±√(33)]/2

Therefore:

[tex]x=\frac{-5+\sqrt{33} }{2}[/tex] and [tex]x=\frac{-5-\sqrt{33} }{2}[/tex]
