Question

The zeros of the quadratic polynomial $x^2+99x+127$ are

• A. Both positive
• B. Both negative
• C. One positive and one negative
• D. Both equal

Answer 1

The correct option is B Both negative

Given polynomial is $x^2+99x+27$
Sum of zeroes $=-99$
Product of zeroes $=27$
$\because$ Sum of zeroes is negative and product of zeroes is positive, this is only possible if both should be negative.
$\therefore$ Both zeros will be negative.
Option B is correct.
