Answer:
A. m and n both are positive is correct choice.
Step-by-step explanation:
We have been given that When factoring a trinomial of the form ax2 + bx + c where a, b, and c are all positive. That means:
a>0
b>0
c>0
Then ac>0 as product of same sign numbers is always positive.
Positive produce ac is possible only when both factors are of same sign.
In this situation, b>0 is possible only if both numbers are positive.
Hence choice A. m and n both are positive is correct choice.
