[(px+q)((r)/(x)+s)],[" et "v=(px+a)(ul(r)+]

Find the derivative of (px + q) (r/x + s) , where p,q,r and s are non zero constants .

Find the derivative of (px + q)/(rx + s) , where p,q,r and s are non zero fixed constants .

If alpha,beta are the roots of the equation px^(2)-qx+r=0, then the equation whose roots are alpha^(2)+(r)/(p) and beta^(2)+(r)/(p) is (i) p^(3)x^(2)+pq^(2)x+r=0 (ii) px^(2)-qx+r=0 (iii) p^(3)x^(2)-pq^(2)x+q^(2)r=0 (iv) px^(2)+qx-r=0

If f (x) ={{:( px^(2) +q,"for " xle 1),( qx^(2) +px +r ,"for " xlgt 1 ):} where q ne 0 is derivable at x =1 ,then

If p,q,r,s in R, then equaton (x^(2)+px+3q)(-x^(2)+rx+q)(-x^(2)+sx-2q)=0 has

If (a-x)/(px) = (a-y)/(qy)= (a-z)/(rz) and p, q, r, be in A.P then x,y, z are in
