IF the equation ax+by=1, ` cx ^2 +dy^2 =1 ` have only one solution then ` (a^2)/(c ) +(b^2)/(d)=`

If the equations ax+by=1 and cx^(2)+dy^(2)=1 have only one solution,prove that (a^(2))/(c)+(b^(2))/(d)=1 and x=(a)/(c),y=(b)/(d)

If the equations ax + by = 1 and cx^2 +dy^2=1 have only one solution, prove that a^2/c+ b^2/d = 1 and x=a/c , y=b/d

The equations x^2+b^2=1-2bx and x^2+a^2=1-2ax have only oneroot in common then |a-b|=

The line ax + by = 1 cute ellipse cx^(2) + dy^(2) = 1 only once if

If the equation ax^2+2bx+c=0 and ax^2+2cx+b=0 b!=c have a common root ,then a/(b+c =

If the equation ax^(2)+2bx+c=0 and ax62+2cx+b=0b!=c have a common root,then (a)/(b+c)=

The equations x^(2)+b^(2)=1-2bx and x^(2)+a^(2)=1-2ax have only oneroot in common then |a-b|=

If the equation ax^(3)+3bx^(2)+3cx+d=0 and ax^(2)+2bx+c=0 have a common root then ((bc-ad)^(2))/((b^(2)-ac)(c^(2)-bd)) is :

If c^(2)=4d and the two equations x^(2)-ax+b=0 and x^(2)-cx+d=0 have one common root. then the value of 2(b+d) ) is equal to (A)? 13 ) ac (C) 2ac(D) ane
