If x + 1/x = 2, then the value of (2x² + 2)/(3x² + 4x + 3) will be:

If x^3 – y^3 = 117/8 and x – y = 3/2 then the value of x^2 + xy + y^2 will be

If x = 1/(√3 + 1), then value of 4x³ − 2x² − 8x + 5 is

If x + (1/x) = 3, then the value of x³ + (1/x³) is :

If x³ + y³ = 35 and xy = 6, x > y, then value of (x − y) will be

If (a² − 1)/a = 2, then the value of (a⁶ − 1)/a³ is:
