प्रश्न

`sqrt3x^2+10x7sqrt3=0` 

उत्तर

We Write : `10xx=3x+7x` as ` sqrt3x^2xx7sqrt3=21x^2=3xxx7x`  

∴ `sqrt3x^2+10x+7sqrt3=0` 

⇒`sqrt3x^2+3x+7x+7sqrt3=0` 

⇒`sqrt3x(x+sqrt3)+7(x+sqrt3)=0` 

⇒`(x+sqrt3)(sqrt3x+7)=0` 

⇒`x+3sqrt3=0` or `sqrt3x+7=0`

⇒`x=-sqrt3 or x=7/sqrt3=(-7 sqrt3)/3` 

Hence, the roots of the given equation are `-sqrt3` and  `-7sqrt3/3`
