To expand the binomial (L-2t)^2, you can use the formula for squaring a binomial, which is (a+b)^2 = a^2 + 2ab + b^2. In this case, let a = L and b = -2t.

Using the formula, we have:
(L-2t)^2 = (L)^2 + 2(L)(-2t) + (-2t)^2

Now, let's simplify each term:
(L)^2 = L^2
2(L)(-2t) = -4Lt
(-2t)^2 = 4t^2

Combining these terms, we get:
(L-2t)^2 = L^2 - 4Lt + 4t^2

Therefore, the expanded form of (L-2t)^2 is L^2 - 4Lt + 4t^2.
