please answer fast ,if you know answer then only answer with full process please​

Answer 1

Step-by-step explanation:

1. The roots of any quadratic equation is given by: x = [-b +/- sqrt(-b^2 - 4ac)]/2a. Write down the quadratic in the form of ax^2 + bx + c = 0. If the equation is in the form y = ax^2 + bx +c, simply replace the y with 0. This is done because the roots of the equation are the values where the y axis is equal to 0.

2. By algebraic identity, (a-b)² = (a+b)² - 4ab.

Using this, (α - β)² = (α + β)² - 4αβ

This shows that α - β = √(α + β)² - 4αβ

Now I think you should know how to solve further. This conversation is already closed by Expert.

3. Given equation has equal roots,

So, its Discriminant, D=0

D= ksquare-4(2)(3)=0

ksquare=24

k=+_√24
