Remember: expanding two binomials (equations with two terms like 3x + 4) will give you a quadratic. For example (x + 5)(x - 1), using FOIL (first, outer, inner, last) will give a trinomial (an equation with three terms):
x2 - x + 5x - 5 = x2 + 4x - 5
If I was just given this last equation, how could I find out what its factors are?
- use the box method.
Here is a powerpoint presentation (that will be run in class). When it is presented, you might want to have downloaded it, and have it open on your netbook so that you can follow it and take notes.
