Question

When a trinomial is factored as (x + m)(x + n), what is the product of m and n?


A.The coefficient of the x-term of the trinomial
B.The constant term of the trinomial
C.The degree of the trinomial
D.The coefficient of the x2-term of the trinomial

Answer 1

Use FOIL:
(x + m)(x + n)
= x^2 + nx + mx + mn

Compare with ax^2 + bx + c:
x^2 = x^2
nx + mx = bx
mn = c, the constant term of the trinomial

Answer 2

so it would be B @mathstudent55

Answer 3

correct
