Question 99175
Let x=the first integer
Then x+1=the second

Now we are told that:
 x(x+1)=156  get rid of parens

x^2+x=156  subtract 156 from both sides

x^2+x-156=156-156 or
x^2+x-156=0   quadratic in standard form and it can be factored:

x+13)(x-12)=0

x=-13------------first integer
x+1=-13+1=-12-----------other integer
and
x=12-------------------first integer
x+1=12+1=13-----------other integer
