I can solve quadratic equations that have complex roots because I'm good enough, I'm smart enough, and doggone it, people like me!

When we are solving equations using the quadratic formula, what is going to cause answers with complex (imaginary) roots?

x^2 - 4x + 5 = 0
x^2 - 4x + 5 = 0
x^2 + 8x + 25 = 0
x^2 + 8x + 25 = 0
2x^2 = -3(2x + 3)
2x^2 = -3(2x + 3)
