Which algebraic expression is a difference with two terms

D

Step-by-step explanation:

A 6(x + 5) ← multiplication

B 9x ÷ 6 ← division of 2 terms

C 6 + x - 9 ← 3 terms

D 6x - 9 ← difference of 2 terms

For this case, we have that by definition, the difference is represented by the mathematical sign "-", also called signs of subtraction or sign of subtraction.

Then we discard options A and B.

We have the option C:

It contains a sign of addition and also refers to three terms.

Finally, in the last option, we have a difference of two terms.

is the first term

is the second term
