It would be -2 - x .
The variable is d, in the algebraic expression 7d+2
Not every algebraic expression is a polynomial. A polynomial consists of terms that are non-negative integer powers of variables, combined using addition, subtraction, and multiplication. In contrast, algebraic expressions can include terms with negative or fractional exponents, such as (x^{-1}) or (x^{1/2}), which do not qualify as polynomials. Therefore, while all polynomials are algebraic expressions, not all algebraic expressions are polynomials.
x-2
7t/2
An algebraic expression
2(-6n)
The variable is d, in the algebraic expression 7d+2
x = 2 is an algebraic equality (Because there is an 'equals'(=) sign) x - 2 is an algebraic expression ( Because there is NO equals sign).
x-2
what is the constant in algebraic experssion 7d+2
Yes. Yes it is ^_^
there are 2
An algebraic expression
7t/2
It is an expression of algebraic terms with no equality sign
It is the same as: -2q-3 as an algebraic expression
