Question

Oneta writes an algebraic expression with three terms. The y-term has a coefficient of -3, and the x-term has a coefficient of 1. The expression does not have a constant term. Which expression could she have written? x minus y squared minus 3 y

Answer 1

x-y²-3y

Explanation:

In algebraic expressions, the coefficient of a term is the number behind the letter or variable.

e.g. The coefficient of b in 7b is 7

The coefficient of g in -5g is -5

Note that we also make use if the sign.

If The y-term has a coefficient of -3,

The term is -3y

The x-term has a coefficient of 1.

The term is x

The expression does not have a constant term.

Since the options are not provided, examples of expressions she could have written can be:

I. x-3y

II. x-3y-y²

III. x-3y-x² and so on.
