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

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

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

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

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

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

If (x+2) is a common factor of (px^(2)+qx+r) and (qx^(2)+px+r) then a p=q or p+q+r=0 b p=r or p+q+r=0 c) q=r or p+q+r=0 d p=q=-(1)/(2)r
