You can put this solution on YOUR website!
Odd integers = x and x+2
(x)(x+2)=143
x%5E2%2B2x-143=0
Use Quadratic Formula: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
a=1, b=2, c=-143
x=%28-2%2B-sqrt%28%282%29%5E2-4%281%29%28-143%29%29%2F2%281%29%29
x=%28-2%2B-sqrt%284%2B572%29%29%2F2%29
Add: x=%28-2%2Bsqrt%28576%29%29%2F2%29
x=11
11+2=13
Hence the two consective integers are 11 and 13.
