Write the linear factorization and solve quadratic

The video tutorial explores solving equations using the square root method instead of the difference of squares, due to 7 not being a square number. It emphasizes leaving answers in exact form rather than approximating. The tutorial further explains the concept of zeros, linear factorization, and multiplicity, demonstrating how to convert zeros into factors and write linear factorizations. The importance of understanding the multiplicity of factors is also highlighted.

Why is it important to leave the square root of 7 as an exact answer rather than approximating it?

Define the term 'multiplicity' in the context of linear factors.
