Lessons can start at any section of the PPT examples judged against the ability of the students in your class. The last equation doesn’t appear to have the variable squared, but when we simplify the expression on the left we will get n2 + n. Listed below are some examples of quadratic equations: x2 + 5x + 6 0 3y2 + 4y 10 64u2 81 0 n(n + 1) 42. Main: Lessons consist of examples with notes and instructions, following on to increasingly difficult exercises with problem solving tasks. Quadratic equations are equations in which the variable is squared.
