`( 3 x + 4) sqrt( 3 x + 7 ) `

If sqrt(3x - 7) + sqrt(3x + 7) = 4 + sqrt(2) then value of x + 1/x is

If x = 7 + 4 sqrt(3) , y = 7 - 4 sqrt(3) , find the value of (1)/(x^(2)) + (1)/(y^(2)) .

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.

Find x if (sqrt(3x +1) + sqrt(3x - 6))/(sqrt(3x + 1) - sqrt(3x - 6)) = 7

If x = 7 - 4 sqrt 3 , then the value of (x + 1/x) is :
