If `1+sqrt(2)` is a root of a quadratic equation with rational coefficients, write its other root.

Text Solution

Verified by Experts

Given that `1+sqrt2` is a root of the quadratic equation with rational coefficient
Then find the other root
as we know that if `1+sqrt2` is a root of the quadratic equation with rational coefficient then other roots be `1-sqrt2`
Hence, the required equation is `1-sqrt2`
