The missing figure in the expression
(5p +...)2 = ....+ 40 pq + 16 q2 are:
4q and 25p2
4q and 5p2
16p and 5p2
4q and 25p
From square identity we know, (a+b)2 = a2 +b2+2ab
(5p+ 4q)2 = 25p2+ 40pq + 16q2
If the point of intersection of the lines 2px+3qy+r=0 and px–2qy–2r=0 lies strictly in the fourth quadrant and is equidistant from the two axes, then
