Question

twice the product of M and N decreased by the square of the sum M and N

which of the following is an expression for the statement above

A) 2mn-(m²+n²)

B) 2mn-(m+n)²

C) (m+n)² -2mn

D)(m²+n²)-2mn

Answer 1

"the product of M and N" mean M•N and twice that is 2•M•N (which can also by written as 2MN).

"the sum M and N" is (M + N) and "the square of the sum M and N" is (M + N)²

So "twice the product of M and N decreased by the square of the sum M and N" is:

2MN - (M + N)²
