Which of these is a variable term in the expression:
–4 x2 + 100 / 2
A. 2 B. –4x2 C. –x2
D. 100
B: -4x^2
terms are separated by +/- signs.
The variable term in the expression –4x^2 + 100/2 is C. –x^2.
To identify the variable term in the expression –4x2 + 100/2, we need to understand what a variable term is.
A variable term is a term in an expression that contains a variable. In this case, we have three terms in the expression: –4x2, 100, and 2.
The term –4x2 contains both a coefficient (-4) and a variable (x2). The coefficient represents the number multiplied by the variable, and the variable is a symbol that can take on different values.
On the other hand, 100 and 2 are constants as they do not contain variables. Constants are values that do not change and remain the same throughout the expression.
Given that information, the variable term in the expression –4x2 + 100/2 is option C: –x2.
