(λx^2 - x + λ^2 - 5) + (x^2 + λ^2x - 4λ)

You haven't actually said what you want, do you just want to simplify it?

(λx ² - x + λ ² - 5) + (x ² + λ ²x - 4λ)

= λx ² - x + λ ² - 5)+ x ² + λ ²x - 4λ

There are no 'like terms' so all you can do is remove the brackets.

Suggestion : questions like this are easier to read if you use the sup (superscrip) button that is located above the smilies.

Now I have a question for you, how did you include the lambda signs in the post? Do you have a special keyboard?
