Two linear expressions can be expanded, and then simplified by collecting like terms, if there are any. Linear expressions have no terms with power of 2 or higher. For example, 15x – 4y is a linear ...

Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align} a_{0,0}x_0 + a_{0,1}x_0 + \cdots a_{0,n-1}x_0 & = b_0 ...

Removing brackets is to multiply the term outside the brackets by each term inside - also known as the distributive law. Use FOIL to remove a pair of brackets then simplify by collecting like terms.
