Question

`sqrt3x^2+11x+6sqrt3=0` 

 

Solution

Given: 

`sqrt3x^2+11x+6sqrt3=0` 

⇒`sqrt3x^2+9x+2x+6sqrt3=0` 

⇒`sqrt3x(x+3sqrt3)+2(x+3sqrt3)=0` 

⇒`(x+3sqrt3)(sqrt3x+2)=0` 

⇒`x+3sqrt3= or sqrt3x+2=0` 

⇒`x=-3sqrt3  or  x=(-2)/sqrt3=(-2xxsqrt3)/(sqrt3xxsqrt3)=(-2sqrt3)/3` 

Hence, the roots of the equation are `-3sqrt3` and `(-2sqrt3)/3`
