in the quardratic equation, pqx^2 - (p^2 +q^2) x +pq = 0, t6he value of x are

x^2-qx-p^2-5pq+6q^2=

If 2010 is a root of x^(2)(1 - pq) - x(p^(2) + q^(2)) - (1 + pq) = 0 and 2010 harmonic mean are inserted between p and q then the value of (h_(1) - h_(2010))/(pq(p - q)) is

If (p + 2) (2q - 1) = 2pq - 10 and (p - 2) (2q - 1) = 2pq - 10, then what is pq equal to ?

If every pair from among the equations x^ 2 + p x + q r = 0, x^2+px+qr=0, x^2 + q x + r p = 0, x^2+qx+rp=0 and x^2 + r x + p q = 0, x^2+rx+pq=0 has a common root then the product of three common root is (A) pqr (B) 2pqr (C) (p^2q^2r^2) (D)none of these

a^(2)p^(2)x^(2)-q^(2)=0,x=

The LCM of two polynomials p(x) and q(x) is x^(3) - 7x + 6 . If p(x) = (x^(2) + 2x -3) and q(x) = (x^(2) + x - 6) , then the HCF is
