Question

alpha^2+beta^2 identity

Answer 1

Explanation:

alpha^2+beta^2=(alpha+beta)(alpha beta)

Answer 2

Answer:

`alpha^2 + beta^2 = (alpha + beta)^2 - 2alpha beta`

Explanation:

α2+β2=(α+β)2−2αβ

Since (a+b)2(α+β)2(α+β)2−2αβ

∴α2+β2=a2+2ab+b2,

             =α2+2αβ+β2

             =α2+β2

             =(α+β)2−2αβ
