This video shows a way to factor quadratics when the leading coefficient is 1. More general quadratics will be presented in a subsequent video. The answers to the practice problems in the video are as follows:
1. (x + 2)(x+ 4)
2. (y- 1)(y - 2)
3. (m - 11)(m + 2)
4. (l + 3)(l + 9)
5. x(x - 6)
6. (x - 3)(x + 3)
7. (2x -5)(2x + 5)
8. 3x(x -5)
9. 2(x - 2)(x -3)
10. 2(x + 2)(x - 1)
