39α= -13/2 β=6 γ=-72/13
with this 2nd and 3rd questions are too easyyyyyyyyyy
just substitute and get the answers.
1st part i donno
Arithmetic,geometric and harmonic mean of the roots of the x2+13x+36=0 are α,β,γ respectively.
1)x1 and x2 are the roots of ax2+bx+c=0, a,b,cεR and α,β,γ lies between x1andx2 δ=mod(x1-x2) then set of all values of δ.
2)set of all vales of t if sum of roots of x2-(t2-13t+α+γ)x-36=0 is less than or equal to β is [l,m] and p=l+m then p is equal to
3)equation whose roots are 2α, p is (where is obtained in qn 2) is
