Answer:
Step-by-step explanation:
alpha will be equal to beta +1
α=β+1
therefore by formula, b
αβ=c/a
β²+β=k
Now we will find value of beta
α=β-1
α+β=-b/a
2β-1=-5
β=-2
therefore,
β²+β=k
k=4-2=2
please mark as brainliest and best of luck for your exam.
misprint because answer ekdum correct hai. trust me
sorry bro galat tha
k=4+2=6
last mein error tha
beta will be 2
since-b/a is 5. sorry meri mistake thi. silly

x2-5x+k
Here, a=1, b=-5 and c=k
Now, α+ β = -b/a= -(-5)/1= 5
α*β = c/a= k/7= k
Now,α - β =1
Squaring both sides, we get,
(α - β)2=12
⇒ α2 + β2 - 2αβ = 1
⇒ (α2 + β2 + 2αβ) - 4αβ = 1
⇒ (α +β)2 -4αβ =1
⇒ (5)2-4k=1
⇒ -4k= 7-25
⇒ -4k= -24
⇒ k=6 So the value of k is 6.
