This intermediate algebra lesson focuses on the solution of quadratic (2nd degree) equations by using the quadratic formula x= (-b ?? square root(b^2- 4ac))/2a This lesson will help you understand how to find the values of a, b & c and solve equations using the quadratic formula when: - answers are in the simplest form - answers must be simplified - there are no real roots - the quadratic equation can be factored - you use your calculator to express answers as decimals Sample question: Solve 2x^2+x=5 This lesson contains explanations of the concepts and 25 example questions with step by step solutions plus 6 interactive review questions with solutions. Lessons that will help you with the fundamentals of this lesson: - 160 Operations with Radicals - 230 Solving Quadratic Equations by FactoringMORE[EDIT]
