If pp and qq are positive integers, then which one of the following equations has p−qp-\sqrt{q} as one of its roots?

Options

  1. Ax2−2px−(p2−q)=0x^2-2 p x-\left(p^2-q\right)=0
  2. Bx2−2px+(p3−q)=0x^2-2 p x+\left(p^3-q\right)=0
  3. Cx2+2px−(p2−q)=0x^2+2 p x-\left(p^2-q\right)=0
  4. Dx2+2px+(p2−q)=0x^2+2 p x+\left(p^2-q\right)=0

Correct answer

B. x2−2px+(p3−q)=0x^2-2 p x+\left(p^3-q\right)=0

Step-by-step solution

The correct answer is option (B).
