B
Correct answer
Explanation
For x^2 + 99x + 127 = 0, the sum of roots is -99 and the product is 127. Since the product is positive, the roots have the same sign. Since the sum is negative, both roots must be negative.
AI explanation
For the quadratic polynomial x^2 + 99x + 127, we compare the signs of the coefficients using the relationship between zeros and coefficients. Since the sum of the zeros is -99, which is negative, and the product of the zeros is 127, which is positive, both zeros must be negative numbers. Therefore, both zeros of the polynomial are negative.
