if alpha and beta are roots of X2+6x+9=0 then find eqn whose roots are 1/alpha,1/beta6x+9=0 About the author Margaret
9x 2 +6x+1=0 α,β are roots of equation x 2 +6x+9=0 α+β=−6 & αβ=9 So, if roots are αα1 , β1x 2−( α1 + β1 )x+ αβ 1=0 x 2 −( α+β )x+ αβ 1=0 x2+ 9 6 x+ 9 1=0 9×2+6x+1=0- Hope this helps you Reply
9x 2
+6x+1=0
α,β are roots of equation
x
2
+6x+9=0
α+β=−6 & αβ=9
So, if roots are
αα1 ,
β1x 2−( α1 + β1 )x+ αβ
1=0
x 2 −( α+β )x+ αβ
1=0
x2+ 9
6 x+ 9
1=0
9×2+6x+1=0-
Hope this helps you
