Comparing Linear and Quadratic Equations

Mrs. Ruccio explains the differences between linear and quadratic equations, focusing on identifying and solving them. The video covers methods for solving linear equations by isolating variables and balancing, and quadratic equations using factoring, the quadratic formula, and inverse operations. Examples illustrate each method, highlighting key characteristics like the presence of x or x squared terms.

What is the highest power of x in a linear equation?
