x^{2}+9x+20=x^{2}+29
Use the distributive property to multiply x+4 by x+5 and combine like terms.
x^{2}+9x+20-x^{2}=29
Subtract x^{2} from both sides.
9x+20=29
Combine x^{2} and -x^{2} to get 0.
9x=29-20
Subtract 20 from both sides.
9x=9
Subtract 20 from 29 to get 9.
x=\frac{9}{9}
Divide both sides by 9.
x=1
Divide 9 by 9 to get 1.
