Solve for x: `sqrt(3x^2)-2sqrt(2)x-2sqrt3=0`
Advertisements
उत्तर
`sqrt(3x^2)-2sqrt(2)x-2sqrt3=0`
Hencea= `Hence a=sqrt3, b=-2sqrt2,c=-2sqrt3`
`x=(-(-2sqrt2)+-sqrt((-2sqrt2)^2-4xxsqrt3xx(-2sqrt3)))/(2xxsqrt3)`
`=(2sqrt2+-sqrt(8+24))/(2sqrt3)`
`=(2sqrt2+-sqrt32)/(2sqrt3)`
`=(2sqrt2+-4sqrt2)/(2sqrt3)`
`=(2sqrt2+4sqrt2)/(2sqrt3),(2sqrt2-4sqrt2)/(2sqrt3)`
`=(3sqrt2)/(2sqrt3),(-2sqrt2)/(2sqrt3)`
`x=sqrt6,-sqrt(2/3)`
