k^{2}+5k+6=k^{2}+13k+22
Use the distributive property to multiply k+2 by k+11 and combine like terms.
k^{2}+5k+6-k^{2}=13k+22
Subtract k^{2} from both sides.
5k+6=13k+22
Combine k^{2} and -k^{2} to get 0.
5k+6-13k=22
Subtract 13k from both sides.
-8k+6=22
Combine 5k and -13k to get -8k.
-8k=22-6
Subtract 6 from both sides.
-8k=16
Subtract 6 from 22 to get 16.
k=\frac{16}{-8}
Divide both sides by -8.
k=-2
Divide 16 by -8 to get -2.
