Find the difference of two quadratic equations to find the domain

The video tutorial explains the importance of correctly subtracting functions by using like terms and grouping symbols. It highlights common mistakes students make, such as not distributing negative signs properly. The tutorial also covers the concept of domains, emphasizing that the domain of the resulting function remains the same when combining functions with all real numbers as their domain.

Discuss the significance of the quadratic and linear equations in the context of function operations.

What can you conclude about the domain of the new function after combining two functions with the same domain?
