Just check b² - 4ac. If it's positive, you've got two real roots. If zero, just one. Negative? No real roots.
The discriminant in a quadratic equation is that magical part under the square root in the quadratic formula, b² - 4ac. It tells you how many real solutions there are!
Take it from me, the discriminant (b² - 4ac) can make or break your day in math class. Know your roots—literally!
