Note that a square of a binomial or product of two binomials always results as a trinomial (three terms). And also, the FOIL METHOD is frequently used to determine the answer in every two binomials. Try to use it and you'll see. :)

my answer is -10x-25xsquared-4x+10
my keyboard does not do any "raising to a power thingy" so put the "squared" word on the x

F = first terms, O = outer terms, I = inner terms, L = last terms
