The sum and the product of the roots of the quadratic equation x(power 2) + 20x + 3 = 0 are?
Correct answer: C. -20, 3
- A. 10, 3
- B. -10, 3
- C. -20, 3
- D. -10, -3
Explanation
For a quadratic x² + 20x + 3 = 0, the sum of roots is -20 and the product of roots is 3, using the relations -coefficient of x and constant term. Therefore the pair is -20, 3. The likely mistake is choosing b, which incorrectly changes the sum to -10, perhaps by dividing the coefficient by 2.

About Quadratic Equations
Quadratic equations contain a squared variable and can be solved by factorisation, completing the square, the quadratic formula, or graphical reasoning. Questions cover roots, the discriminant, and the relationship between roots and coefficients, while distinguishing real and repeated roots from complex or non-real roots.
