Question

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?

a) 2x + z + 5 - 6z^2
b) 2x- z-5 + 2z^2
c) -2 x - z- 5 + 2z^2
d) -2 x + z- 5 + 2z^2

Answer 1

Hi there!

Your answer is:

B) 2x -z -5 + 2z^2

Explanation:

xterm has 2 in front

z term has -1 in front

expression has constant term <0 (means it must be neg)

2x - 1z + (x<0)

Hope this helps
