**bobpursley**, Thursday, October 9, 2008 at 9:43pmlet the integers be n, n+1, and n+2

2n*(n+2)-28=(n+1)^2

solve for n, notice it is a quadratic.

**Stupid**, Thursday, October 9, 2008 at 9:45pmBuy why wouldn't it be n, n+2, and N+4 because it is even ingergers,

**Reiny**, Thursday, October 9, 2008 at 10:51pmyou are right, it should have been

n, n+2 and n+4 so let's adjust bobpursley's equation to look like

2n(n+4) - 28 = (n+2)^2

**Adithya**, Friday, October 17, 2008 at 7:40pmlets start with the equation

2n(n+4) - 28 = (n+2)^2

using formula (a+b)^2=a^2+2ab+b^2

2n^2+8n-28=n^2+4n+32

simplyfying,

n2+4n=32

Solving for n, we get n=4

So the even consecutive numbers are 4,6,and 8.....

checking...

2(4*8)-28=36
