You'd probably start with x being the smallest integer:
I'd start with x being the middle one of the three:
because it would be easy to multiply out (x-1)(x+1)
But heck! x is bound to be near the cube root of 26970,
So pick up a calculator that can take cube roots:
That's close to 30, so try 30 as the middle one
Try 29,30,31
<--That's it!
That's a quick way to get the answer, and since factoring
and solving a cubic equation requires trial and error with
synthetic division anyway, I'd say the above way is the
best way to do it. Other tutors might disagree.
Answer: 29,30,31
