I'm trying to find solution(s) to the following equation:
$x^2 - 5x + 3 = 0$
It seems like it can't be factored normally so I tried solving by completing the square:
$(x-2.5)^2 = -0.5$
That's where I get stuck since you can't get the real number square root of a negative number.
Is there another method I could use to solve this quadratic equation? Did I make a mistake?
