उत्तर
Given that `(1 + sqrt2)` is a root of the quadratic equation with rational coefficients.
Then find the other root.
As we know that if `(1 + sqrt2)`is a root of the quadratic equation with rational coefficients then other roots be `(1 - sqrt2)`.
Hence, the require root of the quadratic equation be `(1 - sqrt2)`.
