No, they were in the first two, which they won

1 Potato, two potato, three potato, four, (five potato, six potato, seven potato more).

You factor it.

81t3 - 81t = 0

Divide by 81:

t3 - t = 0

Take out the common factor t:

t (t2 - 1) = 0

Here we have a difference of two squares, therefore:

t (t + 1) ( t - 1) = 0

If the product is zero, that means that one of the factors must be zero, so you have to solve the three equations:

t = 0 OR t + 1 = 0 OR t - 1 = 0.

In summary, t can be 0, -1, or 1.

Only two teams have won it more than three times. Brazil have won it 5 times and Italy have won it 4 times.

The answer is this: One Two Three Four Five...see the capitol letters...get the pattern? "O" - One "T"-Two "T"-Three "F"-Four "F"-Five Have fun!
