Solved for consecutive odd integers:
.
S=smaller integer; L=larger integer=S+2
.
For S=5:
L=S+2=5+2=7
ANSWER: The numbers are 5 and 7.
.
For S=-1:
L=S+2=-1+2=1
ANSWER: The numbers are -1 and 1.

x(x+2)=6x+5
x^2+2x=6x+5 subtract 6x, both sides
x^2-4x=5 Subtract 5, both sides
x^2-4x-5=0 Now factor the left side
(x-5)(x+1)=0 Separate into 2 equations
x-5=0 or x+1=0
x=5 or x=-1 Go back to the original equation and try each of these possible answers:
5(5+2)=6(5)+5= 35=35 We got our answer, x=5
