Hi there!
How are you?
Answer:
[tex]\boxed{x = + \sqrt{5} |Or| x = 1 - \sqrt{5} }[/tex]
Step-by-step explanation:
First you have to use quadratic formula with [tex]a=1, b=-2, c=-4.[/tex]
[tex]x = \frac{-b \± \sqrt{b^2 -4ac} }{2a}[/tex]
[tex]x = \frac{-(-2) \± \sqrt{(-2)^2 - 4(1)(-4)} }{2(1)}[/tex]
[tex]x = \frac{\sqrt{^2\± \sqrt{20} } }{2}[/tex]
[tex]x = + \sqrt{5}[/tex] or [tex]x = 1 - \sqrt{5}[/tex]
Hvae a good day/night!
