If alpha and beta be the zeores and polynomial 2x²-5x+8 evaluate alph

1.	If alpha and beta be the zeores and polynomial 2x²-5x+8 evaluate alpha/beta+ beta/alpha
Answer» α +β= (-b/a),α+β=5/2,αβ=c/a,αβ=8/2=4, (α+β)^2 = α^2+β^2+2αβ,(5/2)^2=α^2+β^2+825/4-8=α^2+β^2,α^2+β^2=(-7/4)Then, α/β+β/α =α^2+β^2/αβ=(-7/4)/4=(-7/16)
