Quadratic expression: x2 + 90x + 126
Formula used:
Sum of roots = -b / a
Product of roots = c / a
Calculation:
a = 1, b = 90, c = 126
Sum = -90 / 1 = -90
Product = 126 / 1 = 126
Sum is negative ⇒ both roots are negative
Product is positive ⇒ both roots have same sign
∴ The correct answer is option (2): both negative.
