The true statement about the trinomial is (d) m and n are  both negative

How to determine the true statement?

The trinomial is given as:

[tex]x^2 - bx + c[/tex]

The factors are given as:

(x + m)(x + n)

By law of quadratic, we have:

m + n = b

mn = c

When b is negative, and c is positive.

It means that variables m and n have the same sign

This means that:

m and n are  both negative

Hence, the true statement is (d) m and n are  both negative
