A. Solve the following quadratic equations. Make sure to show all your work. Do not use any method (e.g. factoring, completing the square, quadratic formula, graphing) more than twice. Use the graphing method at least once.
1. 3x+2 + 11x 20 =0
2. x2 + 3x 4 =0
3. 3x2  x  1 =0
B. State the different methods you used to solve each equation. Make sure that your work demonstrates both algebraic and graphing methods.
I am so lost on this! Could someone please show me how all of this is done? It will probably be on my tests!
Thanks much!
