Solving Equations by Factoring
It is important you remember how to:
- Solve a linear equation
- How to factor.
Recall what a linear equation looks like.
Examples of linear equations:
3x + 2 = 0
7x + 1

Introduction to factoring
If I take the number 24 and write it as a product as 24 = (4)(6), then I can
say I factored the number 24 as a product of 4 and 6. 4 & 6 are factors of 24.
Definition: Factor
