The perpendicular distance of the plance ax + b y + c z + d = 0 from the point P(x_(0) , y_(0) , z_(0)) is (ax_(0)+by_(0)+cz_(0)+d)/sqrt(a^(2)+b^(2)+c^(2))

What is the difference between 0.9 and 0.9% ? 0.9 और 0.9% के बीच का अंतर है ?

If a, b, c are in G.P then prove that equations ax^(2) + 2bx + c =0 and dx^(2) + 2ex +f=0 have a common root if (d)/(a), (e)/(b), (f)/(c) are in A.P.

If a,b,c are in G.P.L, then the equations ax^(2) + 2bx + c = 0 0 and dx^(2) + 2ex+ f = 0 have a common root if ( d)/( a) , ( e )/( b ) , ( f )/( c ) are in :
