Question

Pick the expression that matches this description:

Answer 1

Answer:

D. $3m^2+m-5$

Step-by-step explanation:

We have been given 4 expressions. We are asked to choose a trinomial with a leading coefficient of 3 and a constant term of -5.

Let us check our given choices one by one.

A. $-5m^2+4m+3$

Upon looking at our expression, we can see that leading coefficient is $-5$ and constant term is 3, therefore, option A is not a correct choice.

B. $3m^2-5$

Upon looking at our expression, we can see that leading coefficient is 3 and constant term is $-5$ . But we can see that this expression is not a trinomial as it has only two terms, therefore, option B is not a correct choice.

C. $3m^2-5m+1$

Upon looking at our expression, we can see that leading coefficient is 3 and constant term is 1 . Therefore, option C is not a correct choice.

D. $3m^2+m-5$

Upon looking at our expression, we can see that leading coefficient is 3 and constant term is $-5$ and expression has three terms. Therefore, option D is the correct choice.
