equation
(x + y)/20
The expression that represents two times the sum of p and 8 is 2(p + 8).
In algebra, an expression consisting of the sum or difference of two monomials (see the definition of monomial), such as 4a-8b.
Equation, not expression. A and B are two numbers. (A + B)2 = A2 + B2 + 2(AB) ----------------------------------
No, it could be a constant.
(x + y)/3
That's either the sum or difference of two cubes.
