Identify the binomial A. x2 - 4x + 2 B. x2 C. x2 - 4 D. 2x2 + 3x - 1 + y

The Correct answer is C) x² - 4.

A binomial is an expression that contains the sum of two distinct terms. In this case, the terms are x² and - 4.

A) Contains 3 terms: x², - 4x, and 2. Notice that, since x and x² have different exponents, they are considered distinct terms (you can't simplify the expression any further, unless you know what the value for x is)

B) Contains only one term, x²

D) Contains 4 distinct terms, 2x², 3x, - 1, and y

The correct binomial is C.
