Question

if one root of quadratic eq. with rational cofficients is 2+√3 , then give other root ​

Answer 1

Answer:

2- √3

Step-by-step explanation:

A quadratic equation (ax^2+bx+c=0) has 2 roots since highest power of x is 2. If one root of a quadratic equation is irrational(2+√3), the other root will also be irrational and it must be the conjugate of the 1st root (2-√3).To get the conjugate root the sign before irrational part of 1st root should be changed.
