1. C

  • The formula for the sum of the roots is -b/a and the formula for the product of the roots is c/a.

2. A

  • The formula for the product of the roots is c/a.

3. D

  • The quadratic expression tells us that it is less than or equal to zero. Wherein ≤ is one of the symbols of inequality.

5. B.

  • This symbol < is read as less than.
  • This symbol ≤ is read as less than or equal to.
  • This symbol > is read as greater than.
  • This symbol ≥ is read as greater than or equal to.
