If `p, q, r` are `3` real number satisfying the matrix equation, `[p q r][[3,4,1],[3,2,3],[2,0,2]]=[3,0,1]` then `2p+q-r` equals

If p,q,r are 3 real number satisfying the matrix equation,[pqr][[3,4,13,2,32,0,2]]=[3,0,1]

If p&q are two real numbers satisfying the relation 2p^(2)-3p-1=0 and q^(2)+3q-2=0 respectivelyand pq!=1, then

if p,q,r are real numbers satisfying the condition p + q +r =0 , then the roots of the quadratic equation 3px^(2) + 5qx + 7r =0 are

if p,q,r are real numbers satisfying the condition p + q +r =0 , then the roots of the quadratic equation 3px^(2) + 5qx + 7r =0 are

Let A=[[0,2q,r] , [p,q,-r] , [p,-q,r]] If A A^T=I_3 then |p|=

Let A=[[0,2q,r] , [p,q,-r] , [p,-q,r]] If A A^T=I_3 then |p|=
