(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Use the disciminant to determine all values of k that would result in the equation x^2 - kx + 4 = 0 having equal roots.

2. Relevant equations

x = -b +/- (square root) b^2 - 4ac and divide by 2a

or b^2 - 4ac

3. The attempt at a solution

a = 1

b = - 1

c = 4

I'm a little confused with this problem because instead of a number by b there's a k.
