This video tutorial covers solving word problems involving linear quadratic systems of equations. It begins with an introduction to the topic and a detailed example of solving a system where f(x) equals 2x squared minus 5x plus 2 and g(x) equals x plus 3. The tutorial then demonstrates using the quadratic formula to solve equations to the nearest tenth. It also includes a practical application of analyzing profit and cost using quadratic and linear functions, followed by modeling attendance at art exhibits with similar equations. The video emphasizes careful reading of problems to determine whether to find x-values or both x and y-values.
