How does the discriminant relate to the quadratic formula

The video tutorial explains the concept of the discriminant in quadratic equations, which is expressed as b squared minus 4ac. It discusses how the discriminant helps determine the nature of the roots: complex, irrational, one real, or two rational roots. The discriminant is a part of the quadratic formula, specifically under the square root. The tutorial emphasizes the importance of finding the discriminant first to understand the type of roots and solve quadratic equations effectively.
