`x^3-x^2-(2-sqrt2)x+sqrt2` check `(x+1)` is value of given polynomial?

If two zeroes of the polynomial x^4+3x^3-20x^2-6x+36 are sqrt2 and -sqrt2 . find the other zeroes of polynomial

The expression (sqrt(2x^2+1)+sqrt(2x^2-1))^6 + (2/(sqrt(2x^2+1)+sqrt(2x^2-1)))^6 is polynomial of degree

If x = sqrt(3)- sqrt(2) find the value of x+(1)/(x)

If x = 3 + 2sqrt(2) check whether x+(1)/(x) is rational or irrational.

The value of f(0), so that the function f(x)=(sqrt(a^2-a x+x^2)-sqrt(a^2+a x+x^2))/(sqrt(a+x)-sqrt(a-x)) becomes continuous for all x , given by a^(3/2) (b) a^(1/2) (c) -a^(1/2) (d) -a^(3/2)

The value of f(0), so that the function f(x)=(sqrt(a^2-a x+x^2)-sqrt(a^2+a x+x^2))/(sqrt(a+x)-sqrt(a-x)) becomes continuous for all x , given by a^(3/2) (b) a^(1/2) (c) -a^(1/2) (d) -a^(3/2)

If x=(sqrt2+1)/(sqrt2-1) ,then x+frac1x=?

If x=sqrt3+sqrt2 , then x+frac1x=

If x = 2 - sqrt 3 , find the value of (x-1/x)^3

If x= 2sqrt(3)+2sqrt(2) find : (1)/(x)
