| 00:0-1 | The classic mistake that students making this problem is to | |
| 00:03 | say that N plus three squared means n squared plus | |
| 00:09 | three squared or n squared plus nine . Remember however | |
| 00:14 | , that N plus three squared means N plus three | |
| 00:18 | times itself or N plus three times N plus three | |
| 00:28 | . So we really have to buy no meals that | |
| 00:31 | are multiplying together . And to simplify this problem , | |
| 00:34 | we must use the foil method . So the products | |
| 00:38 | of the first terms end times in is and square | |
| 00:43 | plus apart to the outer terms end times positive three | |
| 00:47 | is positive three in plus . Apart to the inner | |
| 00:51 | terms positive three times in is positive three in . | |
| 00:56 | Plus upon it to the last terms positive three times | |
| 00:59 | positive three , Which is positive nine combining our middle | |
| 01:04 | terms , we have N squared plus six . N | |
| 01:10 | plus nine for our final answer . Remember whenever you | |
| 01:16 | square a binomial , you must write it out as | |
| 01:20 | that binomial times itself , then foil . |
DESCRIPTION:
This lesson covers the midsegment of triangle. Students learn the following theorems related to parallel lines. If 3 parallel lines form congruent segments along one transversal, then they form congruent segments along every transversal. If a line intersects the midpoint of one side a triangle and is parallel to another side of the triangle, then it intersects the midpoint of the third side of the triangle. If a segment joins the midpoints of two sides of a triangle, then the segment is (a) parallel to the third side of the triangle, and (b) half the length of the third side. Students are then asked to solve problems related to these theorems using Algebra.
