Answer:
if you want to sketch the trapezoid you will also need other dimensions like height and the length of the parallel sides
The difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
<h2>What is
perfect square trinomial?</h2>
A perfect square trinomial is the square of a binomial. It follows a pattern when it is factored, so that the first and last terms are perfect squares of monomials and the middle term is twice their product. If the pattern does not fit for a particular trinomial, it is not a perfect square trinomial.
<h3>How to solve this equation?</h3>
(-2m + 5n)^2
(-2m + 5n)(-2m + 5n)
4m^2-10mn-10mn+25n^2
4m^2 - 20mn + 25n^2
Thus, the difference of squares is 4m^2 - 20mn + 25n^2
Its a perfect square trinomial.
