Add:
5px+7q-r,2px+3r and =px+2q+r.

Add: p ( p – q), q ( q – r) and r ( r – p)

Find the derivative of the following function (it is to be understood that a, b, c, d,p, q, r and s are fixed non-zero constants and m and n are integers): (px + q)(r/x+s)

Find the derivative of the following function (it is to be understood that a, b, c, d,p, q, r and s are fixed non-zero constants and m and n are integers): (ax+b)/(px^2 +qx+r)

Find the derivative of the following function (it is to be understood that a, b, c, d,p, q, r and s are fixed non-zero constants and m and n are integers): (px^2 + qx+ r)/(ax+b)

Let A={p , q , r , s}\ a n d\ B={1,2,3}dot Which of the following relations from A to B is not function? (i) R_(1) = {(p, 1), (q, 2), (r, 1), (s, 2)} (ii) R_(2) = {(p, 1), (q, 2), (r, 1), (s, 1)} (iii) R_(3) = {(p, 1), (q, 2), (r, 2), (r, 2)} (iv) R_(4) = {(p, 2), (q, 3), (r, 2), (s, 2)}

Divide as directed : 52pqr (p + q) (q + r) (r + p) -: 104pq(q + r) (r + p)

Show that if p,q,r and s are real numbers and pr=2(q+s) , then atleast one of the equations x^(2)+px+q=0 and x^(2)+rx+s=0 has real roots.

The roots of Ax^2 + Bx + C =0 are r and s. For the roots of x^2+ px + q = 0 to be r^2 and s^2 , what must be the value of p ?
