Part A: Variables, printing, and control structures 1. Write a piece of code to solve the following quadratic equation for x: 2.5x2 - 17.5x 20.0 = 0 using the quadratic formula. Use variables to store the coefficients, and print the solution(s) as part of a single sentence using string formatting. Use comments to explain what you are doing. You can find basic mathematical functions in the math or numpy modules. Once you are done, run the code, either by pressing the "play" button above, or typing Shift+Enter. [ ]: 2. Try adjusting one or more of the coefficients and run the cell again. Make some notes about what you find in the following markup cell. E.g., First try making some small adjustments to the coefficient values, then try picking coefficients that will give you a complex solution (i.e., where b2 - 4ac
