Read Solution (Total 6)
-
- a=2x
If 0 and 1 are roots, then equation will be
x^2-x=0 - 11 years agoHelpfull: Yes(3) No(0)
- x^2-(sum of roots)x+(product of roots)=0
x^2-(0+1)x+(o*1)=0
x^2-x=0
then compare the equation

- ANS: a= 0 or 2
On substituting x=0 in eqn we get a=0.
On substituting x=1 in eqn we get a=2.
Therefore a=0 or 2.

- a=2x
x^2-3x+2x=0
x^2-x=0
x(x-1)=0
x=0,x=1 - 11 years agoHelpfull: Yes(0) No(1)
- a=0,2 this is possible when a=2x
