Question

Time sensitive question... Pleaseeee help!!

Answer 1

Here is your answer

d)
`r2= -5-√(5)`

REASON:

Equation is-


`2{x}^(2)+8x+c=0`

Here,

a= 2; b= 8 and c=c

Now,


`r1+r2= -b/a`

[Relation used: sum of zeroes=
-coefficient of x/ coefficient of x^2]

So,


`1+√(5) + r2= -8/2`


`1+√(5) + r2= -4`


`r2= -4-1-√(5)`


`r2= -5-√(5)`
