What one root? x%5E2-10x%2B2k=0

x=%2810%2B-+sqrt%28100-4%2A2k%29%29%2F2

x=%2810%2B-+2%2Asqrt%2825-2k%29%29%2F2

highlight%28x=5%2B-+sqrt%2825-2k%29%29-----the solution to the equation. k is still an unknown variable.

If you want Real Number solutions for x, then you must have 25-2k%3E=0;
-
25%3E=2k
2k%3C=25
k%3C=25%2F2
highlight%28k%3C=12%261%2F2%29
