what do these mean to you? 1. simplify linear expressions with rational numbers. 2. factor linear expressions.

1) Simplifying linear expression with rational number means, we are dealing with numbers which are in fraction form, and are proportional to other side.

For Example. - 7x/3 = 21/6
In this example, when we solve for x, it would be rational number & as expression is proportional, it fits best for your question!!

2) Factorization (finding factors) of linear expressions:
For example. - 20 + 40 = 2 * 10 + 4 * 10
Here, linear expression is solved into simpler forms

Hope this helps!
