Question

PLEASE ANSWER! When a trinomial is factored as (x+m)(x+n), what is the sum of m and n?

A. The degree of the trinomial

B. The constant term of the trinomial

C. The coefficient of the x-term of the trinomial

D. The coefficient of the x^2-term of the trinomial

I REALLY NEED THIS ANSWERED

Answer 1

C. The coefficient of the x-term of the trinomial

Again, here's your reason:
(x+m)(x+n)
x^2 +xm+nx +mn
x^2 + x (m+n) + mn


As you can clearly see that the sum of m and n equal the coefficient of x term so, the correct option is C.
