Complete the following activity to solve the quadratic equation `sqrt(3) x^(2) +4x- 7 sqrt(3) = 0` by factorisation method `:`
`sqrt(3) x^(2) +4x- 7 sqrt(3) = 0`
`:. sqrt(3) x^(2) + square - 3x - 7 sqrt(3) = 0`
`:. x( sqrt(3) x + ) - sqrt(3) ( sqrt(3) x + 7) = 0 `
`:. (" ") (x-sqrt(3))= 0 `
`:. sqrt(3) x + 7 = 0 ` or `square = 0 `
`:. x = ( -7)/( sqrt(3)) ` or `x = square `
`:. (-7)/(sqrt(3))` and `sqrt(3)` are the roots of the equation.
