Answer:
D. [tex]3m^2+m-5[/tex]
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. [tex]-5m^2+4m+3[/tex]
Upon looking at our expression, we can see that leading coefficient is [tex]-5[/tex] and constant term is 3, therefore, option A is not a correct choice.
B. [tex]3m^2-5[/tex]
Upon looking at our expression, we can see that leading coefficient is 3 and constant term is [tex]-5[/tex] . 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. [tex]3m^2-5m+1[/tex]
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. [tex]3m^2+m-5[/tex]
Upon looking at our expression, we can see that leading coefficient is 3 and constant term is [tex]-5[/tex] and expression has three terms. Therefore, option D is the correct choice.
