λ^2-2λ=(λ-2)^2

Solution

λ^{2} - 2 λ = (λ - 2)^{2}

Solution

λ = 2

Solution steps

λ^{2} - 2 λ = (λ - 2)^{2}

Expand

(λ - 2)^{2} : λ^{2} - 4 λ + 4

λ^{2} - 2 λ = λ^{2} - 4 λ + 4

Subtract

λ^{2} - 4 λ

from both sides

λ^{2} - 2 λ - (λ^{2} - 4 λ) = λ^{2} - 4 λ + 4 - (λ^{2} - 4 λ)

Simplify

2 λ = 4

Divide both sides by

2

λ = 2
