Question

if one of the roots of a quadratic equation is 3-√2 then find the value of alpha+beta​

Answer 1

Step-by-step explanation:

Let’s taken the equation ax^2 + bx + c = 0.

The roots of this equation are x = [-b + √(b^2 – 4ac)]/ 2a

We can name one root as α [say the one with the positive sign, [-b + √(b^2 – 4ac)]/2a

] and the other as β [the one with the negative sign, [-b - √(b^2 – 4ac)]/2a

]. Then we can easily divide one with the other to get α/ β.
