Question

How do you solve `0 = x^2 - 5/2x + 1/2` using the quadratic formula?

Answer 1

`x^2-2.5x+0.5=0` and `x1=2.28` and `x2=0.219`

Explanation:

Let me calculate delta first: `Delta=b^2-(4*a*c)` where a is 1 b is -2.5 and c is 0.5. Then `Delta=4.25`.

Using solution `x1=(-b+sqrt(Delta))/(2a)` and `x2=(-b-sqrt(Delta))/(2a)`
you can get `x1=2.28` and `x2=0.219`
