If α,β are the roots of the quadratic equation x2 – (a – 2)x – – InterviewSolution

1.	If α,β are the roots of the quadratic equation x2 – (a – 2)x –(a+1) =0, where 'a' is a variable then the least value of α2+β2
Answer» If α,β are the roots of the quadratic equation $x^{2}$ – (a – 2)x –(a+1) =0, where 'a' is a variable then the least value of $α^{2}$ + $β^{2}$
