The root of a quadratic equation in x, are -m and 2n. Find the equation

The root of a quadratic equation in x, are -m and 2n. Find the equation

  • A.
    (x^2 + x(m – 2n)-2mn=0)
  • B.
    (x^2 – x(m – 2n)-2mn=0)
  • C.
    (x^2 – x(m – 2n)+2mn=0)
  • D.
    (x^2 + x(m – 2n)+2mn=0)
Correct Answer: Option B
Explanation

x = -m (implies) x + m = 0;

x = 2n (implies) x – 2n = 0.

(implies (x + m)(x – 2n) = 0)

(x^2 + mx – 2nx – 2mn = 0)

(x^2 + x(m – 2n) – 2mn = 0)
