Given that the equation below has equal roots, find the value of k:
kx² - 4x + k - 3 = 0
I've never seen this before. how would it be done?
Do you know about the discriminant ?
If , then there are 2 distinct real roots.
If , then there are 2 equal real roots (and the polynomial is proportional to a perfect square)
If , then there is no real root.
