7x2x
7x2x is an algebraic expression in which multiplication is implied by juxtaposition. It combines the constants 7 and 2 with the variable x appearing twice. Interpreted in standard algebra, it means 7 × x × 2 × x. By the commutative and associative properties of multiplication, this simplifies to (7×2) × (x×x) = 14x^2. Thus, 7x2x is a monomial of degree 2 with coefficient 14.
The expression has no constant term and no linear term in x; it evaluates to zero when
In programming and computer algebra, explicit multiplication signs are often added to avoid ambiguity (for example,
