If α,β are the roots of equation a(x2−1)+2bx=0, then the equation whose roots are 2 α−1β and 2β−1α is
2αβ−1β=−3β and 2αβ−1α=−3α
If α,β are the roots of the equation ax2 +2bx +c = 0 and α+δ, β+δ are the roots of Ax2 + 2Bx + C= 0 , then b2–acB2–AC =
If α, β are the roots of ax2 +2bx+c=0 and a+δ, β+δ are the roots of Ax2 + 2Bx + C=0 then b2–acB2−Ac is
