Factoring Trinomials Formula
Let’s start with the basic formula. If we have a trinomial in the form ax^2 + bx + c, it can be factored into (px + q)(rx + s). Here, p*r = a, q*s = c, and p*s + q*r = b.
Trinomial Categories
| Range (a) | Level | Interpretation |
|---|---|---|
| 1-10 | Easy | Beginner Level |
| 11-20 | Medium | Intermediate Level |
| 21+ | Hard | Advanced Level |
Examples
| Trinomial | Factored Form | Calculation |
|---|---|---|
| x^2 + 5x + 6 | (x + 2)(x + 3) | 2*3=6, 2+3=5 |
| 2x^2 – 3x – 2 | (2x + 1)(x – 2) | -21=-2, 22-3=-3 |
Calculation Methods
| Method | Advantages | Disadvantages | Accuracy |
|---|---|---|---|
| Factor by Grouping | Simple | Not always possible | High |
| Complete the Square | Always possible | Complex | High |
Evolution of Concept
| Century | Change |
|---|---|
| 17th | Introduction of formula |
| 18th | Further refinement |
