Question 768234: Hello,
My question is "the product of two consecutive positive integers is 29 more than their sum, find the integers".
I don't understand what the computer went over, there were additional steps that confused me, like a whole 2 steps about changing "1n" to "n" when n=1n.
n(n+1)=2n+1 then 2n+1+29=2n+30 then subtract 2n and 30 so that the equation is 2(n+1)-2n-30=0 then this is where I got confused. The next step was n*n+n-2n-30 so n^2-1n-30=0 then the answers are 6,-5. Where do the 6 and -5 come from and is that right, they're not both positive, but changing to 5,6 makes sense but I don't know how to check my answer.
Please help and thank you

You can put this solution on YOUR website! "the product of two consecutive positive integers is 29 more than their sum, find the integers".
----------
x*(x+1) = x + (x+1) + 29
(x-6)*(x+5) = 0
x = -5 (Ignore, it says positive)
x = 6
------
--> 6 & 7
