प्रश्न

Solve:
`3sqrt(2x^2) - 5x - sqrt2 = 0`

योग

उत्तर

Given equation is,

`3sqrt(2x^2) - 5x - sqrt2 = 0`

`=> 3sqrt(2x^2) - 6x + x - sqrt2 = 0`

`=> 3sqrt2x (x - sqrt2) + 1 (x-sqrt2) = 0`

`=> (3sqrt2x + 1) (x - sqrt2) = 0`

`3sqrt2x + 1 = 0 or x - sqrt2 = 0`

`therefore x = -1/(3sqrt2) or x = sqrt2`
