The base BC of a triangle ABC is bisected at the point (p, q) and the equations to the sides AB and AC are respectively $x+y+3=0$ and $qx+py=1.$ Then the equation to the median through A is

Question

Accepted Answer

$2x-y=9$

Answer

$({{p}^{2}}+{{q}^{2}}-1)(px+qy-1)=(2p-1)(qx+py-1)$

Answer

$(pq-1)(px+qy-1)=({{p}^{2}}+{{q}^{2}}-1)(qx+py-1)$
