Question

if a+root b is one of the roots of a quadratic equation , then the other root is?​

Answer 1

Answer:

The other root of a quadratic equation having the one root as (a+√b) is (a-√b).

Step-by-step explanation:

α + β = (a+√b) + (a-√b) = 2a, a rational number and, αβ = (a+√b)(a-√b) = a² - b, a rational number. So, the other root of a quadratic equation having the one root as (a+√b) is (a-√b), where a and b are rational numbers.
