Write the discriminant of the followi...

Write the discriminant of the following quadratic equations: `sqrt(3)x^2+2sqrt(2)x-2sqrt(3)=0` (ii) `x^2-x+1=0`

Text Solution

Verified by Experts

The correct Answer is:
`x=sqrt(6)" or "x=(-sqrt(2))/(sqrt(3))`
`sqrt(3)x^(2)-2sqrt(2)x-2sqrt(3)=0impliessqrt(3)x^(2)-3sqrt(2)x+sqrt(2)x-2sqrt(3)=0`
`" "impliessqrt(3)x(x-sqrt(6))+sqrt(2)(x-sqrt(6))=0.`
