  • a)
    X2 – X – 20 = 0
  • b)
    X + X + 20 = 0
  • c)
    X2 + X – 20 = 0
  • d)
    X2 – X + 20 = 0
Correct answer is option 'A'. Can you explain this answer?

If sum of the roots of a quadratic equations is 1 and product of the r...
Sum of roots = 1
Product of root = – 20
Quadratic equation ⇒ X2 – (Sum of root) X + (Product of root) = 0
⇒ X2 – (1) X + (– 20) = 0
⇒ X2 – X – 20 = 0
Hence, required quadratic equation will be X2 – X – 20 = 0
