Solve `sqrt3x^2-2sqrt2x-2sqrt3=0`
उत्तर
`sqrt3x^2-2sqrt2x-2sqrt3=0`
⇒`sqrt3^2-3sqrt2x+sqrt2x-2sqrt3=0`
⇒`sqrt3x(x-sqrt6)+sqrt2 (x-sqrt6)=0`
⇒`(x-sqrt6) (sqrt3+sqrt2)=0`
⇒`x-sqrt6=0 or sqrt3x+sqrt2=0`
⇒`x=sqrt6 or x=-sqrt2/sqrt3=-sqrt6/3`
Hence,` sqrt6 and -sqrt6/3` are the roots of the given equation.
