 Questions 5 Topics Factoring Quadratics, Line Segment, Pythagorean Theorem, Quadratic Equations, Two Variables

#### Study Guide

To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.

###### Line Segment

A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.

###### Pythagorean Theorem

The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, $$c = \sqrt{a + b}$$
