Hassan writes an algebraic expression with four terms. The x-term has a coefficient of 2, and the z-term has a coefficient of -1. The expression has a constant term less than zero. Which expression could he have written?
We will write the expression step by step according to what the problem poses. We have then: The x-term has a coefficient of 2: [tex]2x
[/tex] the z-term has a coefficient of -1: [tex]2x - z
[/tex] The expression has a constant term less than zero: [tex]2x - z - 5
[/tex] Then, the complete expression is: [tex]2x - z - 5 + 2z ^ 2
[/tex] Answer: B. 2x - z - 5 + 2z ^ 2
