Which of the following equations can be solved by the points of intersection P and Q of the curve and the line PQ?

  • A.
    x2 – 2 = 0
  • B.
    x2 – 4 = 0
  • C.
    x2 + 6 = 0
  • D.
    X2 – X – 2 = 0
  • E.
    x2 – x + 4 = 0
Correct Answer: Option B
Explanation

The points of intersection of the curve and the line are at x = -2 and x = 2.

(therefore) (x + 2) = 0; (x – 2) = 0.

(x + 2)(x – 2) = 0

(x^2 – 4 = 0)
