This video tutorial covers the segment addition postulate, explaining that if a point lies between two endpoints on a line segment, the sum of the two smaller segments equals the entire segment. The tutorial includes three examples: a simple calculation, an algebraic expression, and a quadratic equation, demonstrating how to apply the postulate in different scenarios.

What does the Segment Addition Postulate state?

If you have a line segment AB and a point B between AC, then AB + BC = AC.

If you have a line segment AB and a point C between AB, then AC + BC = AB.

If you have a line segment AC and a point B between AB, then AB + AC = BC.

If you have a line segment AB and a point C between AC, then AB + AC = BC.

In the third example, what is the quadratic equation formed when AB = X^2 + 7X, BC = 3X + 2, and AC = 26?

X^2 + 7X + 3X + 2 = 26

X^2 + 10X - 24 = 0

X^2 + 7X + 3X + 2 = 0

X^2 + 10X + 2 = 26
