The first is about **solving** square **equations** by factorying. The second is in **solving** multi-deviation **equations** using the reproductive. **Quadratic equations** can be factored into two binomials. Because of the multiplicative property of zero, once of those binomials must equal zero, which allows students to determine the 1 or 2 possible values of x. For example: x 2 + 4 x + 3 = 0 can be factored into. ( x + 3) ( x + 1) = 0. So, x + 3 = 0 or x + 1 = 0.

To **solve** a one step **equation** all you need to do is inverse the operation that is being performed on the variable. Adding – subtracting. Multiplication – Dividing.
