consecutive intergers word problems

[rubyred07]

I cant convert this into an algebra equation

Find three consecutive positive intergers such that the squar of the third is 51 more than the sum of the first and second

 

[Gene]

The three numbers are x-2, x-1 and x. The equation is
x² = x-2 + x-1 + 51

I worked out the problem for you on video. I set up the problem differently but it still works out the same. Instead of letting x represent the largest integer as Gene did, I let x represent the smallest integer.

Sorry about the small writing and my pencil malfunction half way into the video...
