Suppose that the quadratic equations `3x^(2)+px+1=0` and `2x^(2)+qx+1=0` have a common root then the value of `5pq-2p^(2)-3q^(2)=`

If the quadratic equation 3x^(2) + ax+1=0 and 2x^(2) + bx+1=0 have a common root , then the value of the expression 5ab-2a^(2)-3b^(2) is

If the quadratic equations 3x^(2)+ax+1=0 and 2x^(2)+bx+1=0 have a common root then the value of expression |2a^(2)-5ab+3b^(2)| is where (2a!=3b) (A) 0 (B) 1 (C) -1 (D) None of these

If the equations x^(2)-x-p=0 and x^(2)+2px-12=0 have a common root,then that root is

If the equations px^(2)+qx+r=0 and rx^(2)+qx+p=0 have a negative common root then the value of (p-q+r)=

The equations x^(2)-2x+1=0,x^(2)-3x+2=0 have a common root then that common root is

If the equations px^2+2qx+r=0 and px^2+2rx+q=0 have a common root then p+q+4r=

If quadratic equations x^(2)+px+q=0 & 2x^(2)-4x+5=0 have a common root then p+q is never less than {p,q in R}:-
