toring Just one of the methods we will use in College Algebra to solve quadratic equations Another method we will use is the quadratic formula This formula can give use some messy expressions to evaluate so let s practice using our calculator to evaluate the expressions and then simplify the answers as much as possible to 2 2 4 1 3 2 1 1 You may want to simplify the inside of the radical first To evaluate 2 4 1 3 you d type the following into your calculator Ex Evaluate TI calculator 2 2 4x1x 3 Casio calculator 2 x 12 4x1x3 2 Now let s evaluate the rest We have 2 4 2 2 16 2 Since we know 16 Then we d split it up and calculate the two answers separately 2 4 What did you get and 2 4 2 we can simplify that further Pa
