Add :
`1/2 pq, -1/3 pq`

Add 2/5 to 1/3

Find the value of 2p^2q-3pq^2+2p-3p+1 when p=3,q=-3

Divide - 80p^(3)q by -30 pq^(3)

Add 2pqr^2-p^2q+pq and 3p^2q-ab+2

If 2010 is a root of x^(2)(1 - pq) - x(p^(2) + q^(2)) - (1 + pq) = 0 and 2010 harmonic mean are inserted between p and q then the value of (h_(1) - h_(2010))/(pq(p - q)) is

P(0, 3, -2), Q(3, 7, -1) and R(1, -3, -1) are 3 given points. Find vec (PQ)

If PQ is a focal chord of the ellipse 25 x 2 ​ + 16 y 2 ​ =1 Which passes through S=(3,0) and PS=2 then length of the chord PQ is equal to

Multiply : 5p^(2) + 25pq + 4q^(2) by 2p^(2) - 2pq + 3q^(2)

If p + q = 7 and pq = 12 , then will is the value of 1/(p^2) + 1/(q^2) ?
