JNU SSS 2011 Question 5: Quantitative aptitude and data reasoning

If ppp and qqq are the roots of the equation x2−bx+c=0x^2 - bx + c = 0x2−bx+c=0, then what is the equation if the roots are (pq+p+q)(pq + p + q)(pq+p+q) and (pq−p−q)(pq - p - q)(pq−p−q)?

Plain-text version

If p and q are the roots of the equation x² - bx + c = 0, then what is the equation if the roots are (pq + p + q) and (pq - p - q)? (A) x² - 2cx + (c² - b²) = 0 (B) x² - 2bx + (c² + b²) = 0 (C) bcx² - 2(b + c)x + c² = 0 (D) x² + 2bx - (c² - b²) = 0

Also written as: If p and q are the roots of the equation x^2 - bx + c = 0, then what is the equation if the roots are (pq + p + q) and (pq - p - q)?
