Question

23. The quadratic equation whose one root is (3+2/3) is ​

Answer 1

Answer:

x^2 - 6x - 3 = 0

Step-by-step explanation:

Given: One root 3+2√3

Solution:

Now we have given the root of unknown equation as 3+2√3.

So x = 3+2√3

x - 3 = 2√3

Squaring on both sides, we get:

(x - 3)^2 = (2√3)^2

x^2 + 9 - 6x = 12

x^2 + 9 - 6x - 12 = 0

x^2 - 6x - 3 = 0
