You have seen factors of numbers. Here we introduce factors and factoring polynomials. This is the process of rewriting a polynomials as a produce of polynomials of lesser degree.
What are first differences? When given a function or a table of values representing a function, looking at the first difference can help you determine what kind of relationships there is between the variables and hence what function the points represent.
The vector equation of a line is another form of interpreting a line but now with a different structure called a vector. Again, we will see a parameter in this form. A single parameter indicating that we are representing a linear relationship.
When we are faced with a quadratic that is not “nice” to factor we need to find a way to factor it. This is where the quadratic formula comes in. The discriminant is a value that can be calculated for each quadratic equation. Depending on the value of the discriminant, we can determine if the quadratic equation has a solution, or has factors, or not.
