Question

Which of the following is/are INCORRECT?

• A. $4x^2$ is a monomial
• B. $x+2$ is a monomial
• C. $x^2+7x+5$ is a linear polynomial
• D. $x^2+2x+3$ is a bionomial

Answer 1

Answer: (B), (C), (D)

A.
$x^2+7x+5$ is not a linear polynomial because the degree of the polynomial is 2.
Therefore, the statement is incorrect.
B.
$4x^2$ is a monomial because it contains one non zero term.
Therefore, the statement is correct.
C.
$x+2$ is not a monomial because it contains two non zero terms.
Therefore, the statement is incorrect.
D.
$x^2+2x+3$ is not a binomial because it contains more than two non zero terms.
Therefore, the statement is incorrect.
