Hi guys,
Need some help on something I didn't know I didn't know.
How do you factorize this?
-λ3+7λ+6=0
I assumed this?
-λ(λ2-7) + 6 = 0
λ = 6
λ = ±√7
But that's wrong as the answers in the book are -2, -1, and 3.
Can someone give me a little guidance on this, I have only ever done factorization where one of them is already know.
Kind Regards
Rob K
