40 - 3k + 10k = -10 - 8k - 10
40 + 7k = -10 - 8k - 10
40 + 7k = -8k - 20
40 + 7k - 40 = -8k - 20 - 40
7k = -8k - 60
7k + 8k = -8k - 60 + 8k
15k = -60
15k/15 = -60/15
k = -4
We have been given an expression
. We are asked to factor the given expression by grouping.
First of all, we will make two groups of our expression as:

Now we will factor of greatest common factor from each group.


Now we will factor out common terms
as:

Therefore, the factorized form of our given expression would be
.
