`(px+q)((r)/(x)+s)`

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

If the equation px^(3)+3qx^(2)y+3rxy^(2)+sy^(3)=0 (p,q,r,s!=0) represents three coincident lines,then (A) (p)/(q)=(q)/(r)=(r)/(s) (B) pr=qs (C) q=s (D) p=r

Simplify : (px - q)(px + q)

int (px+q)/(sqrt(x^(2)+r^(2)))dx

If ((p)/(q))^(rx-s)=((q)/(p))^(px-q), then find the value of x.

If px + qy + r = 0 and qx + py + r = 0 (x != y) , then show that the value of x + y " is " (-r)/(p) or (-r)/(q)

If 3 - 4i is a root of x^(2) - px + q = 0 where p, q in R . then value (2 p - q)/( p + q) is

If q^(2)-4pr=0,p>0 then the domain of the function f(x)=log(px^(3)+(p+q)x^(2)+(q+r)x+r)
