Question

Which of the following algebraic expressions is/are binomial expression(s)?

• A. $9x+6y$
• B. $7-4$
• C. $2x+5-2y$
• D. $x^{2}y+6xy$

Answer 1

Answer: (A), (D)

The correct options are
A $9x+6y$
D $x^{2}y+6xy$

• $9x+6y\text{has exactly two terms.}\text{Hence it is a binomial expression.}$

• $7-4=3\text{has only one}\text{term. Hence it is a monomial}.$

• $2x+5-2y\text{has three terms.}\text{So, it is a trinomial.}$

• $x^{2}y+6xy\text{has two terms and hence}\text{it is called a binomial.}$
