Answer 1

@iambatman

Answer 2

\[-1+ or - \sqrt{41}/10\]

Answer 3

How did you get that

Answer 4

The Discriminant
y=5x2+1x−2 discriminant =b2−4(a)(c)=12−4(5)(−2)=41 ( 2 real solutions )

The Work
−b±b2−4(a)(c)‾‾‾‾‾‾‾‾‾‾‾√2(a)−1±12−4(5)(−2)‾‾‾‾‾‾‾‾‾‾‾‾‾√2(5)−1±41‾‾‾√10
The Actual Solutions
x=0.5403124237432848 x=−0.7403124237432849

Answer 5

it wont let me make the right signs hold on.

Answer 6

okay
