Question

Factoring Trinomials by Grouping.

Does anyone know how to solve one of these problems?

k^2 + 2k + kt + 2t

Thank you!

Answer 1

=k(k+2)+t(k+2)
=(k+t)(k+2)

Answer 2

So you would just group the two terms then the other two then factor out?
I tried to factor out k from the first group then t from the second but after regrouping the outside terms, the two groups were not the same?
I am probably now explaining this correctly.
