Answer:
plzz mark it as brainliest
correct option is [B]
Step-by-step explanation:
We know that,
In a quadratic expression ax²+ bx + c
If a , b , c will have the same sign
then the both zeroes of the
expression are negative
Compare given expression
x² + 99x + 127 with ax² + bx + c ,
a = 1 , b = 99 ,c = 127
All are positive sign ,
Therefore ,
The expressions both zeroes has negative sign.
Option B ) is correct.
I hope this helps you.
