To find this, we need to find factors of the last number (-30) that add up to the middle number (29). In order to do this, list out all of the factors of -30.
-1 and 30
1 and -30
2 and -15
-2 and 15
3 and -10
-3 and 10
Since -1 and 30 satisfy both of the parameters, we put them into their own parenthesis along with x.
