22m+n^ 2+2n-12

Step-by-step explanation:

5m+n^ 2+20m+n-3m+n-12

(5m+20m-3m) + n^ 2 + (n+n) - 12

22m+n^ 2+2n-12

Chaya Quinn · Answer 2

(m+n+4) (5m+5n-3)

Step-by-step explanation:

5 (m+n) ^2+17 (m+n) - 12

m+n=k 5k²+17k-12 = 5k² - 3k + 20k-12 = k (5k-3) + 4 (5k-3) = (k+4) (5k-3)

(m+n+4) (5m+5n-3)
