Question

Is x+by-z a binomial,trinomial or a monomial

Answer 1

The expression
`x+by-z` is trinomial expression

Why is this correct?

The expression
`\(x + by - z\)` is categorized as a trinomial based on its composition:

• It comprises three distinct terms:
  `\(x\), \(by\)` (a term with the variable
  `\(y\)` multiplied by a coefficient), and
  `\(-z\)`.

• Each term consists of either a single variable
  `(\(x\), \(y\), \(z\))` or a variable combined with coefficients
  `(\(by\))`.

Hence,
`\(x + by - z\)` meets the criteria of having three terms, encompassing a combination of variables and constants, thus qualifying as a trinomial expression.
